Please review and close if this has been done for 9.0.1

There is already a 'Search' module in our release testing:
https://wiki.transvar.org/display/ITD/Search

And 9.0.1 has passed this testing.
The module is short. I think it should be expanded (see below) but I don't think this should delay the release of 9.0.1, I think it should just be a general improvement to our test process as we move forward.
The search module currently does NOT include:
A link to review the user guide.
Search based on properties
Search based on keyword
Search using "|" (pipe) operator
Search using regular expressions

The user guide page (https://wiki.transvar.org/display/igbman/Advanced+Search) includes an image that has an option to search remote servers.
The only text referencing the option is "Only data already loaded into the IGB viewer will be searched unless also search remotely is checked."

I don't think IGB offers that option any more.
So the user guide page should be updated.

Modified task:
Expand the Search module in the release testing (as outlined in the comment).

This does not need to be associated with 9.0.1, and does not need to delay the release.

In the users guide, one of the regular expression option is:
(?i) - use case-insensitive matching

As far as I know, IGB's search is always case-insensitive.
I think we should remove this note from the users guide.

I added tests to the search module in the release testing and I modified the Advanced Search page in the user guide to reflect the current state of the features.

This does not affect the IGB code base, so I don't think it needs a first level review.
I'm marking this as complete.
