Class AnalyzerQueryNodeProcessor

This processor verifies if ANALYZER is defined in the QueryConfigHandler. If it is and the analyzer is not null, it looks for every FieldQueryNode that is not WildcardQueryNode, FuzzyQueryNode or IRangeQueryNode contained in the query node tree, then it applies the analyzer to that FieldQueryNode object.

If the analyzer return only one term, the returned term is set to the FieldQueryNode and it's returned.

If the analyzer return more than one term, a TokenizedPhraseQueryNode or MultiPhraseQueryNode is created, whether there is one or more terms at the same position, and it's returned.

If no term is returned by the analyzer a NoTokenFoundQueryNode object is returned.
