Jeremy Ruston a8f70b08a8 Add indexes to the wiki store to improve performance (#3951) ... * First pass at modular wiki indexes An exploratory experiment * Fix tests * Faster checking for existence of index methods We don't really need to check the type * Use the index for the has operator * Fix typo * Move iterator index methods into indexer modules Now boot.js doesn't know the core indexers * Fix up the other iterator index functions * Fix crash with missing index branch * Limit the field indexer to values less than 128 characters * Fallback to the old manual scan if the index method returns null * Sadly, we can no longe re-use the field indexer to accelerate the `has` operator, because the index now omits tiddlers that have field values longer than the limit Still need to make the index configuration exposed somehow * Rearrange tests so that we can test with and without indexers We also need to expose the list of enabled indexers as a config option * Test the field indexer with different length fields So that we test the indexed and non-indexed codepaths		2019-05-24 21:07:37 +01:00
