DataSource Controls :: Searches Using Full Text Index And 'contains' Fail When Include 'noise Words'?
Mar 11, 2010
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 am using ContainsTable() to perform a full text search on a field (of type varbinary()) and am I wondering if there is a good way to return an excerpt of text around at least one location where the keyword matched the text in the field.Example:User searches for "computer science".The following sentence exists in the varbinary() field: "This book is about computer science and other IT related fields."I would like to return an excerpt around the words "computer science", something like: "...book is aboutcomputer science and other IT..."

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:
[Code]....

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

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 would like to do an attachment on my database but I lost the full-text catalogs file. Sql server won't let me attach the database without it. What do I need to do to overcome this issue? Is there a way to tell Sql Server to skip the missing catalogs? If not, how do I generate another full-text catalogs file to replace to lost one?

This is my first time using autocomplete. I have everything up and running, but I want to return a list of more relevent keywords or phrases from my full text catalog, or the table that I search against. I have no idea where to start as far as my getcompletionlist goes.
So If I type in knee
a list appears
kneepads
here's my getCompletionList
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()
Dim items As New List(Of String)
Dim myConnectionString As String
myConnectionString = GetSQLConnString()
Dim mySelectQuery As String = "SELECT ShortDescription FROM ProductInfo WHERE FREETEXT(ShortDescription, @prefixText) OR FREETEXT(LongDescription, @prefixText) OR FREETEXT(ProductHTML, @prefixText) OR FREETEXT(PartNumber, @prefixText) ORDER BY RANK()
OVER (Order BY PartNumber, ShortDescription, LongDescription)"

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
[Code]....

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?

[RegularExpression(@"S*[a-zs]S*s*", ErrorMessage = "Please add
category name letters only")]
This works fine if I input some words something like this...test test. But if I try to do this... test test test, I will get the ErrorMessage that I implemented. The thing is that I don't know how many words are going to put in by the end user. Is there a way where unlimted whitespaces could put in place? I am using VS2010

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)?

ive an access database with a table, in this table there is only one data column and one counter column (id, pet) i want to draw random a record. Reading on the web i came with this SQL solution: "SELECT TOP 1 tab_pets.pet FROM tab_pets ORDER BY Rnd(id)" and it works perfectly.
The problem is while using this statement in my code behind (in a class) as it draw always the same record, hence generates the same random each time. I though that the access Rnd() function would be handled by the access driver and not by my application, how can i resolve this?
