q
The q
parameter is normally the main query for the request. See Solr query syntax
for more information on different types of queries and syntaxes.
query.setQuery("*:*");
query.setQuery("keywords: \"LP kind 199\"");
query.setQuery("*:* AND NOT seq:a4ec88f8-e0d8-4841-8b02-a88b778d3aa6");
query.setQuery("*:* OR -seq:a4ec88f8-e0d8-4841-8b02-a88b778d3aa6");
sort
query.addSortField("senddatetime", ORDER.desc);
start
query.setStart(0);
rows
query.setRows(20);
pageDoc and pageScore
fq
"fq" stands for Filter Query.
This parameter can be used to specify a query
that can be used to restrict the super set of documents that can be
returned, without influencing score.It can be very useful for speeding
up complex queries since the queries specified with fq are cached
independently from the main query. Caching means the same filter is used
again for a later query (i.e. there's a cache hit). See SolrCaching
to learn about the caches Solr uses.
query.addFilterQuery(" senddatetime:");
query.addFilterQuery(" senddatetime:");
Caching of filters
fl
This parameter can be used to specify a set of fields to return,
limiting the amount of information in the response.When returning the
results to the client, only fields in this list will be included.
query.setFields("keywords description seq");
df
df stands for default search field.
query.setQuery("1316779836");
query.set("df", "mobile");
