[support] indexing and search specific user fields in D7

[Serhat Sevki Dincer]

Greetings,

Suppose I have added some text fields, say field_name, field_surname
and field_address to my users (admin/config/people/accounts/fields in
Drupal 7). I would like to index and search data in the fields
field_name and field_surname only (not field_address). In D7 the
included search module enables searching for usernames and emails
only; I cannot search for specific user fileds. Is there a module for
adding this functionality? I am not looking for a fancy solution like
Solr, it is a small site, just simple, quick and dirty, I want to be
able to search my users in two specific fileds. What should I do? What
do suggest?

Thanks,
Serhat
