Class SearchTokenizer

org.apache.olingo.server.core.uri.parser.search.SearchTokenizer

public class SearchTokenizer
extends Object

searchExpr = ( OPEN BWS searchExpr BWS CLOSE / searchTerm ) [ searchOrExpr / searchAndExpr ] searchOrExpr = RWS 'OR' RWS searchExpr searchAndExpr = RWS [ 'AND' RWS ] searchExpr searchTerm = [ 'NOT' RWS ] ( searchPhrase / searchWord ) searchPhrase = quotation-mark 1*qchar-no-AMP-DQUOTE quotation-mark searchWord = 1*ALPHA ; Actually: any character from the Unicode categories L or Nl, ; but not the words AND, OR, and NOT ATTENTION: For a searchPhrase the percent encoding is not supported by the SearchTokenizer.
This was a decision based on that the org.apache.olingo.server.core.uri.parser.Parser already handles in his parseUri method each query as percent decoded strings (see line 177ff (for (RawUri.QueryOption option : uri.queryOptionListDecoded)).
