public static org.apache.solr.common.params.SolrParams getLocalParams(String txt, org.apache.solr.common.params.SolrParams params) throws SyntaxError
"foo" returns null "{!prefix f=myfield}yes" returns type="prefix",f="myfield",v="yes" "{!prefix f=myfield v=$p}" returns type="prefix",f="myfield",v=params.get("p")- Throws:

toString
public static void toString(org.apache.lucene.search.Query query, IndexSchema schema, Appendable out, int flags) throws IOException
- Throws:
IOException
- See Also:
toString(Query,IndexSchema)
-
toString
public static String toString(org.apache.lucene.search.Query query, IndexSchema schema)
Formats a Query for debugging, using the IndexSchema to make complex field types readable.The benefit of using this method instead of calling
Query.toString
directly is that it knows about the data types of each field, so any field which is encoded in a particularly complex way is still readable. The downside is that it only knows about built in Query types, and will not be able to format custom Query classes.
-
toString
public static List<String> toString(List<org.apache.lucene.search.Query> queries, IndexSchema schema)
Builds a list of String which are stringified versions of a list of Queries
-
parseOP
public static QueryParser.Operator parseOP(String operator)
Parses default operator string into Operator object- Parameters:
operator
- the string from request- Returns:
- Operator.AND if string equals "AND", else return Operator.OR (default)
