Background
With 6.2 and Lucene/Solr, it was possible to do some searching using the Lucene syntax with boolean operators and wildcards:
https://dev.liferay.com/discover/portal/-/knowledge_base/6-2/searching-for-content-in-liferay#advanced-searching
Lucene's QueryParser was used to parse the input "keywords" into a Lucene query supporting the standard syntax so it could interpreted the operators and other special characters.

Current situation
With Liferay 7, switched to a new approach: it uses specific queries using the Query APIs to construct the expected query for a given field such as Match, Phrase, Keyword, Range, TermRange etc. It creates a Query StringQuery (which is for to support parsing in Elasticsearch and Solr) only as a fallback when none of the built-in query-translators can be applied to the input.
End result, advanced searching is not implemented with this new approach.

Request
Add support for Lucene-based syntax so that it can be used with Elasticsearch as well as Solr.

QA Test Plan
NOTE: This will not be testable with Solr until LPS-74053 is resolved. While LPS-74053 is still unresolved, it can be tested by disabling the "Did you mean:" spell check feature.

1. Create wiki pages with the following data:

   Wiki1: title: liferay content: wiki1
   Wiki2: title: portal content: wiki2
   Wiki3: title: java content: wiki3
   Wiki4: title: wiki4 content: liferay portal java lucene
   Wiki5: title: wiki5 content: liferay portal java
   

1. Configure Search Portlet -> Other Settings > Enable "Use Advanced Search Syntax"

Test 1

1. Search for title:(liferay OR java)
   Expected: Search returns 2 results - (Wiki1, Wiki3) 

Test 2

1. Search for title: liferay OR content: liferay
   Expected Search should return 3 results - (Wiki1, Wiki4, Wiki5)

Test 3

1. Search for content: (liferay AND !lucene)
   Expected Search should return 1 result - (Wiki5)

Test 4
TBA (Please add more.)
