Please excuse this question, but I'm new to SQL queries.I want to search on a field, it's a varchar field.
I'm using:
SELECT * FROM table1 WHERE field LIKE "searchterm"
My problem - If I use "lead based paint" for my search term, and I know I have 10 records that exist, how can I get them all to show if I enter terms such as:
lead paint
lead-based paint
etc?
Should this field be indexed?
TIA for any help.

If you whant it to be more un precise this is what you do
SELECT * FROM produkts WHERE produktspecs LIKE "%searchterm%"
if you type lead
it will find lead, leadpaint, paintlead, everything that holds the char "lead"
if you only have "searchterm%"
it will find the ones that start with lead but not the ones that endy with lead...

Thanks for the reply, but I'm already using
%searchterm%. The problem is that this is a field from a search form. The entry in the database is "lead-based paint". If I enter "lead", I get results. With "paint" I get results. With "lead paint", there's no results. Any ideas?

Instead of LIKE try using CONTAINS

Try Breaking up separate words entered in the Search text field. For example if the user enters - lead based paint - the search will look for matches with lead and based and paint.
