DataSource Controls :: Multi Worded Full Text Index Search On 2 Columns?
Jan 12, 2011
I am having with the a full text index I am developing for a product catalog. It does all work to a degree I am just seeing some strange things happening.
From the database side I have a Products table that is being indexed on both the PartNumber and Description columns because I would like the users to be able to search either or using the search function.
Problem 1:
whenever I use multiple words in the search I don't always get the results I am looking for, this happens most notably when I am attempting to say put in a full part number (which for in this case would look like "I 10-9.2")
Problem 2:
I am not 100% sure that this is the most efficient way of completing what I am attempting to accomplish here since I have 2 columns that I need to perform the search on
Here is an excerpt from the click even when the user clicks the search button on the page:
[Code]....
And here is the search functions called from the click event to firstly check if there are any results and the second to display the results in a custom gridview:
How i can make the normal search string to sql server full text search parse, because when we are user enyer search text "how to run windows schedule in C#", in database we have article to to this, but data not returning and sometime is say error in key word and etc.
I want a word search i doing the search like this , but it is giving character wherever there is in the string,if i give two character like ok it is searching for a full string where ever Ok is there select * from table1 where textfield like '%word%' this query would match word but also wordabc how can i make it aware of delimitions
I created a simple search form which populates a gridview from sql server. I use 'contains' on a varchar(max) field which has a full text index. I find if I do a search for "Mexico Argentina", I get multiple results, which is good.One thing my sql server stored procedure is doing is inserting the word 'AND' between words. I do this because I want all words to be found. So if the user inputs "Mexico Argentina", I am converting that to "Mexico AND Argentina"But if I have even one 'noise word' in the search string, I get no results at all. For instance, there might be a sentence in my database table saying "I prefer Mexico to Argentina" but if I put that sentence in, I get no results at all. The database is seeing my converted string:I AND prefer AND Mexico AND to AND ArgentinaAnd finds nothing.I also have another form, which does a more advanced search that allows 'exact phrase'. If the user chooses 'exact phrase', then I don't insert AND anywhere. Instead, I surround his phrase with 4 apostrophes - 2 before the phrase, and 2 after.So now the database sees:' ' I prefer Mexico to Argentina ' ' (I've put a space between apostrophes here to make it clearer to view.Now I not only get no results, I get an error message.
I'm new with all stored procs - but I have a very basic Full Text Search going on...I created a stored proc, and linked it up to my application using Linq to SQL. If I use Linq to SQL to call the stored proc without any parameters (hard coded search string) i get results back, as soon as I add a parameter - the result set is 0 for some reason.
The funny thing is that I run Profiler and execute both queries its trying to do - and it looks identical
Here is the working parameterless query:
[Code]....
and according to Profile this is what it looks like when its called as a stored proc
[Code]....
I get 2 results as expected. Here is the NON-working stored proc that takes in 1 string parameter
[Code]....
and here is the query that gets called when profiling
I have a website which uses full text search. It was working fine on my web host. LAst month, I changed hosting to godaddy.com. They dont support full text search and now my website is not working properly. what change should i make in my stored procedures that they work same as they work with full text. what is alternative to full text search. I tried using LIKE but it doesnt work same way.
I am actually using 2 type of queries in my website e.g
These Queries are from my stored procedures
SELECT * FROM TblName WHERE FREETEXT(ColumnName, @parameter)
AND
SELECT * FROM TblName WHERE CONTAINS((Column1, Column2), @parameter))
I have enabled Full Text Indexing on my tables both local and on my hosting company MS SQL Server.
The above queries are working fine on my local database and return results but these queries return nothing when i try to run them on hosting company MS SQL Server.
I have identical data on both MS SQL Servers and both servers are 2008.
I have installed sql server 2008 express along with visual web developer 2008 express (latest sp1) using web installer now I downloaded this file:
'Microsoft® SQL Server® 2008 Express with Advanced Services' from here: [URL] but when I run the installer and choose add new features to existing instance of sql server I get no full text search feature option in the list, There are only a few options that are selected and greyed out (because they are installed previously) in the list of available features. Why I don't have full text search feature in the list and how to find and install it? (mine is the 64bit version)
I'm implementing an AJAX autocomplete feature where the user types into a textbox and the webpage generates suggestions (pretty much like how Google's search box works). I got the AJAX part to work right, but for some reason, my database query does not.Let's say I want to find "Chicago". Using the following query does not find it.SELECT TOP 10 citynames FROM city WHERE CONTAINS(citynames, 'chi*')But using this query does.SELECT TOP 10 citynames FROM city WHERE CONTAINS(citynames, 'chicago')By the way, "citynames" is an ntext type field and I'm using SQL SERVER 2008.Does anyone know why my first query can't find "Chicago"? I've been staring at that query for hours, yet can't find anything wrong with it. Something wrong with the database maybe?
I am working on a website hosted with GoDaddy, SQL Server 2005. I have a table in my SQL Server database with a full-text index. On my website, a user can type in search terms and the terms are then passed to a stored procedure in the database which performs the search. The first search takes about 45 seconds to get results. Subsequent searches return results immediately. I found a description of this problem in a Microsoft knowledgebase article:http://support.microsoft.com/kb/915850/en-usGoDaddy tech support says I need to purchase a dedicated server to make the changes suggested in this article.Surely there is some other solution. Does anyone know how to avoid this delay without changing the server configuration?
I know about the benefits that full text indexing provides when indexing columns that contain LOB such as varbinary(max), varchar(max) etc. But is there an overhead involved when using full-text indexing and full text search on columns that contain a small amount of data, such as varchar(50)?
Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
Developing a full featured search in my web application. so that in search for data in grid view or data list control and also for search for pages containing search text.

whcih sql server full text search(FREETEXT,CONTAINS and etc) is best article site?
I have a few columns in the table. (E.g. Name, ID, Phone, Address, Father name) and I have a text box where user can type in and the system will show match result on the page. User will only key in Name and Father name in the text box. I do not want to implement a full text search or indexing.
I want to implement full text search using Entity framework in C# 2010. Is there any way to implement this ? I have searched a lot but unable to find the solution.
I have created procedure for full-text search and it works in SQL Management Studio 2008 (SQL Server 2008 Express) but in Visual Studio 2010 not - I have error:Full-Text Search is not installed, or a full-text component cannot be loaded.I have read somewhere that only admin can use full-text indexes - so how I can use full-text search in VS2010 ?
I am using SQL2008 and created a full-text index on 1 of my tables. Going through the wizard, I was offered (2) types of population schedules as follows:New Table Schedule: Define a population schedule for a table.New Catalog Schedule: Define a population schedule for a full-text catalog.I am familiar with a 'Catalog' schedule for population which I do nightly and was similar to configuration on SQL2000 for a full text index. However, what is the difference for a 'Table' schedule vs the 'Catalog' population schedule? I have the definitions above, but if someone with knowledge could offer a better in depth explanation in comparison, and if I should use both or not (I have just a Catalog population scheduled currently),
I Have a table containing columns Address1,Address2,Address3,State,City and Area.Now i want to apply search Location where there will be a single textbox where the user can enter multiple strings seperated by spaces and then those rows should be fetched which contains all these strings entered by the user (implementing AND Case). For which the search on rows should be applied by merging the data of all the above mentioned columns and then searched.How to implement the above case?
I am creating a web app to search thousands of records for past 60 days. I am using SQL stored proc to do the full text search and return the results order by RANK and insert datetime.
I am using custom paging in stored proc to receive 10 results at a time. Each time a page of 10 record is returned it comes up with few records that were added recently and others which were added 40,50 or 60 days ago. This happens because full text search find those results more relevant than the recently added ones.
What would be the best way to sort the results by rank as well as by date time. I am using SQL Server 2008.
