As a random, Liferay custom search developer you might want to get support for Boolean operators and|or Lucene syntax back. Also, it would be nice to have more control of hits relevancy and about the logic, the queries are being built in the end. To get those, we are going a little deeper than before.
Liferay SearchContext is a wonderful transport assistant made for you if you want to implement your custom search easily. You just put your keywords and filtering options there, throw it to, typically FacetedSearcher, and that’s it. But there’s a counter side for this easiness, the amount of control.
When you do like just described, you don’t have control which fields are being searched for in different assets. Nor can you control which query type to use. Especially the query type matters. You may have wondered how standard search gives sometimes even surprising results. Well, it’s because of three things. First, it relies mostly on Elasticsearch MatchQuery (for more information please see the Elasticsearch Query DSL documentation). MatchQuery is the all-rounder of the query types matching, for my likings, too broadly everything. The other thing is that when you execute search, fields are being targeted with multiple different types of SHOULD queries: a WildCard, Match, Phrase and Phrase Prefix –queries. The third thing is that queries are targeted to fields that you, as a guest user, might not be even aware about, like assetTagNames and assetCategoryNames.
So for example a search with phrase “lorem ipsum” transforms through standard search portlet into something like this (2229 lines):

So, where did over 2000 rows go? Ok, this is not completely a fair comparison. I'm using here StringQuery which basically does on one row all the dirty work and searches for all the fields (this topic will be revisited in the next episode). Also, the standard search portlet and this one have very different goals, different emphasis and also different functionalities.
What this exercise shows however, is the strength of Liferay as development platform. The search framework is robust and flexible allowing you to self define the level of control you want to gain.
What was done?
The key things in this solution were:
- Handling the query building manually i.e. not pushing keywords to SearchContext object
- Building the search filters manually
- Using IndexSearchHelper service instead of FacetedSearcher to do the work. It gives you more control.
For the rest of the stuff I'm encouraging you to see the code in Github.
What's still coming
In this part of the series we took more control over building the queries but there's more to do. At the moment the ElasticSearch StringQuery type, we are using, is not implemented fully in portal search.That's why we cannot yet control field level boosting in combination with it.
For those purposes, in the next episode I'm going to customize the Elasticsearch adapter to support ES 5.6 and implement String Query properly. Also I'm going to show you how to use Audience Targeting in Liferay search.
The final planned episode will be about search federation. About using external systems index data through Liferay search.
