[jira] [Commented] (SOLR-5655) Create a stopword filter factory that is (re)configurable, and capable of reporting its configuration, via REST API

["Timothy Potter (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-5655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13898360#comment-13898360 ] 

Timothy Potter commented on SOLR-5655:
--------------------------------------

Should have provided some details about the API ...

To activate, you would need to declare a filter in schema.xml as:

    <fieldType name="managed_en" class="solr.TextField" positionIncrementGap="100">
      <analyzer>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="org.apache.solr.rest.schema.analysis.ManagedStopFilterFactory" managed="english" />
      </analyzer>
    </fieldType>

To see the list of managed stopwords for the "english" handle:

curl -i -v "http://localhost:8984/solr/<collection|core>/schema/analysis/stopwords/english"

This would return a JSON object/map that looks like:

{
  "initArgs":{"ignoreCase":"true"},
  "initializedOn":"2014-02-10T16:23:55.247Z",
  "managedList":[
    "a",
    "an",
    "and",
    "are",
    "as", … ] }

To add some stop words to the set, you'd do:

curl -v -X PUT \
  -H 'Content-type:application/json' \
  --data-binary '["foo"]' \
  'http://localhost:8984/solr/<collection|core>/schema/analysis/stopwords/english'

You can also just get a single word, which will raise a 404 if it is not in the set:

curl -i -v "http://localhost:8984/solr/<collection|core>/schema/analysis/stopwords/english/the"

Lastly, just to be clear, none of the changes made by the API will be "applied" to the underlying analysis components (in this case the StopFilter) until the core is reloaded.

> A stopword filter factory could be (re)configurable via REST API by registering with the RESTManager described in SOLR-5653, and then responding to REST API calls to modify its init params and its stopwords resource file.
> Read-only (GET) REST API calls should also be provided, both for init params and the stopwords resource file.
> It should be possible to add/remove one or more entries in the stopwords resource file.
> We should probably use JSON for the REST request body, as is done in the Schema REST API methods.
