    OK, so this is doing a column search: LIKE '%terry%' note the
    wildcard at the start and end of the string, the one at the start is
    a bit of a killer, it means it can't use an index to rapidly find
    the answer, it has to do a brute force search on all the records and
    do a substring search of the firstname. If you can compromise and
    only allow starts with searches then you can make this way faster,
    so hack the code so that the query is LIKE 'terry%' and add an index
    on the firstname and emails columns it will be pretty much instant -
    at the cost of not allowing you to search for values in the middle
    of the field. <br>
    You can also look at the things you are joining on, <br>
    vtiger_leaddetails.leadid <br>
    vtiger_leadsubdetails.leadsubscriptionid<br>
    vtiger_crmentity.smownerid <br>
    vtiger_crmentity.crmid<br>
    vtiger_users.id<br>
    vtiger_groups.groupid<br>
    <br>
    and make sure they are all indexed, along with
    vtiger_leaddetails.converted which is in the where clause. You can
    see things more clearly if you do an explain of the query, you will
    see some bits require looking at loads of rows, others hardly any,
    if you add an index in the right place then the number of rows it
    needs to look at to perform your query will go down.<br>
    There is a slight cost to indexing things, in terms of disk space
    and insert performance so try to only index things that need it -
    although, if users are adding their own filters with column searches
    that could be pretty much everything. <br>

                queries then you need to index the relevant columns,
