We are using Solr 8.9.0. We have configured Solr cloud like 2 shards and each shard has one replica. We have used 7 zoo keepers for Solr cloud. Our schema field is like <field name="title" type="text_string" indexed="true" stored="true" multiValued="false" omitNorms="true" termVectors="false" termPositions="false" termOffsets="false" omitTermFreqAndPositions="true"/> <dynamicField name="AIR_ts_s_*" type="text_string" indexed="true" stored="true" omitTermFreqAndPositions="true"/> <fieldtype name="text_string" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.KeywordTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.KeywordTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldtype>
We are using sorting and faceting on both field title and AIR_ts_s_100. We see the both field in fieldCache using admin panel and it is taking much memory. After the long time it is not decreasing. We know the we can not apply docValues true directly in solr.TextField. So, We have taken reference from https://github.com/grossws/solr-dvtf. It is working fine for title like after applying sort and facet on title field we can not see in fieldCache but when we are applying sort on AIR_ts_s_100 then we are getting ERROR org.apache.solr.common.SolrException: can not sort on multivalued field: AIR_ts_s_100 of type: text_string at org.apache.solr.schema.SchemaField.checkSortability(SchemaField.java:188) at org.apache.solr.schema.FieldType.getSortedSetSortField(FieldType.java:732) at org.apache.solr.schema.TextField.getSortField(TextField.java:121) at org.apache.solr.schema.SchemaField.getSortField(SchemaField.java:154) Can you please suggest us why we are getting ERROR like can not sort on multivalued field? because it is not multi value true. Our main issue is day by day increasing the fieldCache size. How can we avoid or reduce size for solr.TextField? Regards, Vishal
