Hi all
I'm looking for a way to search and find those tickets which their
subject starts with 'FAX'.
When I use "subject matches 'fax'" in advanced search, the search
query is something like
....
main.Subject LIKE '%FAX%'
...
But I'm looking for a way to have a query with higher performance like
....
main.Subject LIKE 'FAX%'
...
Is there any way to make this query?
Yes, there is. I did the same thing because it kills performance each
and everytime someone searches for something. Only thing is you need to
make your users aware of the fact that including % is now needed if they
don't know the exact search term.
I think you'll find the pre/post pending of % in SearchBuilder but I'm
not completely sure so let me check.....
Yes, its in SearchBuilder.pm the following is part of a patch that I
applied to our installation. Its here for reference only. Don't think
you can paste it to a file and apply it.
