-------------------------------------------
Summary: Provide example scoring.similarity.stopword.file
Key: NUTCH-2206
URL: https://issues.apache.org/jira/browse/NUTCH-2206
Project: Nutch
Issue Type: Bug
Components: plugin, scoring
Affects Versions: 1.11
Reporter: Lewis John McGibbney
Assignee: Lewis John McGibbney
Fix For: 1.12
The scoring-similarity plugin does not provide an example file for the property
scoring.similarity.stopword.file.
This is an issue for a number of reasons, namely
* A user does not know what it is meant to look like, and
* We always check of this file and will [throw an exception if it is not
found|https://github.com/apache/nutch/blob/trunk/src/plugin/scoring-similarity/src/java/org/apache/nutch/scoring/similarity/cosine/DocumentVector.java#L79-L80],
this may not be picked up by the user until much later.
I suggest a simple fix here, simply include the [standard English stop words
taken from Lucene's
StopAnalyzer|https://github.com/apache/lucene-solr/blob/3f38aba02ce37c6422875d8824ee034d42d635b9/solr/contrib/morphlines-core/src/test-files/solr/collection1/conf/lang/stopwords_en.txt].
The comments will help people to easily customize the list to whatever they
require.
