Hybris Solr failed to load core - solr

Question

I am new to hybris and trying to load my apparel store data. Whenever I perform an ant initialize, I get the following error:
org.apache.solr.common.SolrException: Could not load conf for core mProduct: Plugin init failure for [schema.xml] fieldType "string": Error loading class 'de.hybris.platform.solrfacetsearch.ysolr.similarity.FixedTFIDFSimilarityFactory'.

This is how my localextensions.xml looks like:

Is there anyway I can resolve this issue ?

Answer 1

It looks like the jar file that contains FixedTFIDFSimilarityFactory is not found when core is loaded. It should be either in the lib directory or referenced in solrconfig.xml. Perhaps the location the library is put into is different from where your Solr/core is.

Answer 2

The jar library mentioned by #Alexandre is hybriscomponents.5.5.1.0.jar (or the newer one: solr-hybris-components-7.4.3.jar). The package of class FixedTFIDFSimilarityFactory has changed with the version of the JAR file.
All you need to do is change all references from:
de.hybris.platform.solrfacetsearch.ysolr.similarity.FixedTFIDFSimilarityFactory
into:
de.hybris.platform.lucene.search.similarities.FixedTFIDFSimilarityFactory
inside all your schema*.xml files.
