Areek Zillur created SOLR-5378:
----------------------------------
Summary: Suggester Version 2
Key: SOLR-5378
URL: https://issues.apache.org/jira/browse/SOLR-5378
Project: Solr
Issue Type: New Feature
Components: search
Reporter: Areek Zillur
The idea is to add a new Suggester Component that will eventually replace the
Suggester support through the SpellCheck Component.
This will enable Solr to fully utilize the Lucene suggester module (along with
supporting most of the existing features) in the following ways:
- Dictionary pluggability (give users the option to choose the dictionary
implementation to use for their suggesters to consume)
- Map the suggester options/ suggester result format (e.g. support for
payload)
- The new Component will also allow us to have "beefier" Lookup support
instead of resorting to collation and such. (Move computation from query time
to index time) with more freedom
In addition to this, this suggester version should also have support for
distributed support, which was awkward at best with the previous implementation
due to SpellCheck requirements.
Example query:
{code}
http://localhost:8983/solr/suggest?suggest.dictionary=mySuggester&suggest=true&suggest.build=true&suggest.q=elec
{code}
Distributed query:
{code}
http://localhost:7574/solr/suggest?suggest.dictionary=mySuggester&suggest=true&suggest.build=true&suggest.q=elec&shards=localhost:8983/solr,localhost:7574/solr&shards.qt=/suggest
{code}
Example config file:
{code}
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">FuzzyLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">cat</str>
<str name="weightField">price</str>
<str name="suggestAnalyzerFieldType">string</str>
</lst>
</searchComponent>
{code}
