Class MultiPhraseQuery
MultiPhraseQuery is a generalized version of PhraseQuery, with an added method Add(Term[]).
To use this class, to search for the phrase "Microsoft app*" first use
Add(Term) on the term "Microsoft", then find all terms that have "app" as
prefix using MultiFields.GetFields(IndexReader).GetTerms(string), and use Add(Term[])
to add them to the query.
Collection initializer note: To create and populate a MultiPhraseQuery in a single statement, you can use the following example as a guide:
var multiPhraseQuery = new MultiPhraseQuery() {
new Term("field", "microsoft"),
new Term("field", "office")
};Note that as long as you specify all of the parameters, you can use either Add(Term), Add(Term[]), or Add(Term[], Int32) as the method to use to initialize. If there are multiple parameters, each parameter set must be surrounded by curly braces.
