QueryBuilder

open class QueryBuilder(var analyzer: Analyzer = StandardAnalyzer())

Creates queries from the Analyzer chain.

Example usage:

QueryBuilder builder = new QueryBuilder(analyzer);
Query a = builder.createBooleanQuery("body", "just a test");
Query b = builder.createPhraseQuery("body", "another test");
Query c = builder.createMinShouldMatchQuery("body", "another test", 0.5f);

*

This can also be used as a subclass for query parsers to make it easier to interact with the analysis chain. Factory methods such as newTermQuery are provided so that the generated queries can be customized.
