getBooleanQuery
protected org.apache.lucene.search.Query getBooleanQuery(List<org.apache.lucene.search.BooleanClause> clauses) throws SyntaxError
Description copied from class:SolrQueryParserBase
Factory method for generating query, given a set of clauses. By default creates a boolean query composed of clauses passed in.Can be overridden by extending classes, to modify query being returned.
- Overrides:
getBooleanQuery
in classSolrQueryParserBase
- Parameters:
clauses
- List that containsBooleanClause
instances to join.- Returns:
- Resulting
Query
object. - Throws:
SyntaxError
-
addAlias
public void addAlias(String field, float tiebreaker, Map<String,Float> fieldBoosts)
Add an alias to this query parser.- Parameters:
field
- the field name that should trigger alias mappingfieldBoosts
- the mapping from fieldname to boost value that should be used to build up the clauses of the DisjunctionMaxQuery.tiebreaker
- to the tiebreaker to be used in the DisjunctionMaxQuery- See Also:
SolrPluginUtils.parseFieldBoosts(java.lang.String)
-
getAlias
protected ExtendedDismaxQParser.ExtendedSolrQueryParser.Alias getAlias(String field)
Returns the aliases found for a field. Returns null if there are no aliases for the field- Returns:
- Alias
-
getFieldQuery

- Overrides:
getFieldQuery
in classSolrQueryParserBase
- Throws:

in classSolrQueryParserBase
- Throws:
SyntaxError

-
getAliasedQuery
protected org.apache.lucene.search.Query getAliasedQuery() throws SyntaxError
Delegates to the super class unless the field has been specified as an alias -- in which case we recurse on each of the aliased fields, and the results are composed into a DisjunctionMaxQuery. (so yes: aliases which point at other aliases should work)- Throws:
SyntaxError
