#35454: applied a small part of this patch (mentioned in comment #4),
 to fix parsing of user:"user name" syntax generated by advanced search

Fix to issue #27267, advanced search form settings display toggle, supplied in part by Robert Castelo.

Move node specific search pages out of advanced search form and into the menu (as suggested items). This cleans up the advanced search form a bit.

Implement #26181: "Exclude taxonomies from advanced search"

Implement #26182: "Cannot select more than one term per vocab in advanced search"

Implement #25619: "searching filenames/descriptions of attachments"

Fix #25385: "flexinode ID in "filter results by content type""

Implement theme('placeholder') in a bunch of places

The exclude option on advanced search was excluding more nodes than it should have

#26109: "Usernames with spaces not supported in Advanced Search	» Use autocomplete for Usernames in Advanced Search" is a bit less burdensome since we now use this feature only for sites with more than 1000 active users

fix #26107: "date criteria partially ignored"

#26104 "popup calendar ignores date format" is now a bit less burdensome because of better documention

in INSTALL.txt, I noted that this module works with highlight.module if installed.

- added missing css attribute
- simplified comment count

formatted an error message as such

Fixed pagination (issues #25377 and 25029, fix provided by drupal.org user anantagati).  Added support for highlighting in search results pages.
