* Fix search method for search tokens spread across fields Addresses GH #3636, which reports that if you're searching for "test body", and "test" only appears in the title field, and "body" only appears in the text field, 5.1.18's search method won't yield that tiddler as a result, which appears to be a regression from the 5.1.17 behavior * Add test for searching for multiple tokens across fields Verifies GH #3636: > If I create a tiddler in the empty edition with the title "Test tiddler" and content "Body content", searching the wiki for "test body" yields no results under either "title matches" or "all matches". Searching for either word individually turns up "Test tiddler", and repeating this in an empty wiki I created from the 5.1.17 tag causes "Test tiddler" to show up under "all matches".

Extension methods for the $tw.Wiki object

|
|
Adds the following properties to the wiki object:
|
|
|
|
* `eventListeners` is a hashmap by type of arrays of listener functions
|
|
* `changedTiddlers` is a hashmap describing changes to named tiddlers since wiki change events were last dispatched. Each entry is a hashmap containing two fields:
|
|
modified: true/false
|
|
deleted: true/false
|
|
* `changeCount` is a hashmap by tiddler title containing a numerical index that starts at zero and is incremented each time a tiddler is created changed or deleted
|
|
* `caches` is a hashmap by tiddler title containing a further hashmap of named cache objects. Caches are automatically cleared when a tiddler is modified or deleted
|
|
* `globalCache` is a hashmap by cache name of cache objects that are cleared whenever any tiddler change occurs
