Handle single-word phrases enclosed in quotes as phrase queries in search parsing

[marevol]

We will modify the parsing process to treat single-word terms enclosed within double quotes as phrase queries. This change aims to allow users to search for exact phrases, even if the phrase is just a single word.

The planned changes will involve updating the QueryParser.java class:

1. We will introduce a new LuceneQueryParser class that extends org.apache.lucene.queryparser.classic.QueryParser.
2. In LuceneQueryParser, we will override the getFieldQuery method to handle the specific case where a quoted term should be processed as a PhraseQuery instead of a TermQuery.
3. We will also add a splitField method to assist in handling default fields and field extensions.

These modifications will help refine the search functionality to meet our users' expectations for phrase searching capabilities.

The specific code changes are as follows:

• Replace ExtendableQueryParser with LuceneQueryParser, which contains the updated logic.
• Implement the custom getFieldQuery method to check for quoted terms and build a PhraseQuery accordingly.
