For anybody that implemented fuzzy searches in SQL Server or any other
database for that matter. I have implemented edit distance algorithm,
specifically q-grams, in SQL Server and wanted to get some opinions
from anyone who used a similar algorithm in a DBMS.
We are looking to implement fuzzy address search and are employing
number of different techniques including synonyms for strings like
"drive", "dr", "drv", etc... Number expansion, so 6 ave = Six Ave =
6th Ave = 6... Now, we also have an implementation of edit distance
algorithm, which would cover misspellings and similar sounding words.
One of the challenges is putting various techniques together. Synonyms
and number expansion techniques go well together but no edit distance.
Also, I am trying to figure out how to leverage edit distance
implementation for 'contains' searches. So if a string like
'Mississippi Municipal Building' would be returned if the Search is for
'Misisipi Municipal'.
Any thoughts?

Have you checked out the text extraction and fuzzy grouping stuff in SQL
Server Integration Services in SQL Server 2005, I've not used it on
addresses yet, but keyword searches and posts from these forums - quite
interesting results too!
Give it a wurl, its not got the options but it does work.

To search a word in a group of words, say a paragraph or a web page,
would a string search or a regexp search be faster?
The string search would of course be,
if str.find(substr) != -1:

And the regexp search assuming no case restriction would be,

Hi There
I am creating a search page and need help writing the code to build the sql
string.
I have 3 fields on the main page which a user can choose to enter search
terms in any of the 3 fields. My question is how do I write the logic so it
only includes the fields in the search criteria where the user has entered
anything.

I have a string which I need to know where it came from in a database.
I don't want to spend time coding this so is there a ready made script
which takes a string as a parameter and searches all the tables which
contain varchar type columns and searches these columns and indicate which
tables contain that string?
Full text search is not enabled.

Hello there
I need a way to efficiently check if a string I specify can be found in
another string.
For example, if I look for the string "searchString" in the string "jlh ahs
dalskd" then it is of course NOT found, but if I instead look for the same
string in "lkasjalskj searchString sedlfksd" then it IS found.
So, is there any (fairly) efficient way to do this?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
