WIP: Experiment: Advanced search qualifiers

[StevenDufresne]

Mentioned in: meta:3158.

Allow some basic search qualifiers to make searching a little bit more powerful.

Filter by type:
You can combine multiple types to filter.

• type:hook
• type:function
• type:method
• type:class

Filter by file:
You can filter within 1 or more files. Will match partial paths. Uses name__like.

• file:wp-settings.php

Filter by version:
You can filter within 1 version. Must be a full version.

• version:4.8.0

---

Examples:
Search: version:4.8.0 file:class-wp-editor.php get

See version 4.8.0, file: class-wp-editor.php, looking for functions that have get in them.

Returns:

• _WP_Editors::get_baseurl()
• _WP_Editors::get_mce_locale()

Oh.. Well this breaks some of this code :D

I guess I should've done this instead, @StevenDufresne does my change look proper this time?

Suggested change

	if ( str_contains( $s, '(' ) ) {
	// Modify the search query to omit the parentheses.
	$keyword = rtrim( $keyword, '()' );
	if ( str_contains( $s, '(' ) ) {
	// Modify the search query to omit the parentheses.
	$keyword = str_replace( array( '()', '(' ), '', $keyword );

I've updated the code to use the str_replace again. It appears to work. 👍

I think this works well, the only problem I don't have a solution for is that the search query and the filter boxes can fall out of sync seeing that we don't automatically append the advanced search qualifiers when using the filter boxes.

For example:

1. Start with a query type:hook get
2. Search
3. Click [] Methods

It will apply the filter but the search keyword will still be type:hook get but in reality it will be searching like:type:hook type:method get.

I don't think we want to add/remove to the searchbox everytime a checkbox is clicked though... 🤔
