All Implemented Interfaces:

QueryParserConstants

Deprecated.

public abstract class StreamingQueryParser
extends MultiFieldQueryParser

Streaming multi-field query parser.

Allows to preprocess given search term by one or more parser proxies. Parser proxies are chained, i.e. outcome from the first serviceProxy is an income for the next serviceProxy. Chains are created by concatenating serviceProxy names by pipe (|) with the search term as the last element of the chain. Example:

  ontology|stemer|river

Example above passes search term river to the parser serviceProxy called stemer then outcome from stemer is passed further to ontology serviceProxy.

Another example:

  ontology|"colorado river"

This example shows that entire string colorado river is passed to the ontology serviceProxy.

Proxy names are case-insensitive.
