I have a SOLR 4.10.2 core, and I am upgrading to 8.1.1.
I created an 8.1.1 core manually using the default_config set , and then
brought over settings into the 8.1.1 schema
I have adjusted the schema.xml and solrconfig.xml, and I have the core
queryable in 8.1.1.
I have a field named Company:
<field name="Company" type="string" indexed="true" stored="true"/>
<field name="IDX_Company" type="text_general" indexed="true" stored="false"
multiValued="true" />
<copyField source="Company" dest="IDX_Company"/>
In 4.10.2 when I run the query:
IDX_Company:blue
with debugQuery on, I see the query parsed into pieces (correctly)
"debug": {
"rawquerystring": "IDX_Company:blue",
"querystring": "IDX_Company:blue",
"parsedquery": "(IDX_Company:b IDX_Company:bl IDX_Company:blu
IDX_Company:blue)/no_coord",
...
When I run this against 8.1.1, with debugQuery on, I get the following:
"debug":{
"rawquerystring":"IDX_Company:blue",
"querystring":"IDX_Company:blue",
"parsedquery":"IDX_Company:blue",
...
It seems to not be applying the EdgeNGramFilterFactory - the only change I made
to the EdgeNGramFilterFactory configuration was to remove the "side" attribute,
per the documentation.
Also, per the documentation, I replaced the SynonymFilterFactory with
SynonmGraphFilterFactory, and added the FlattenGraphFilterFactory.
I have tried removing the FlattenGraphFilterFactory, I have cleared and
repopulated the core (reindexed), I have stopped and started SOLR 8.1.1, and no
difference.
Here is the definition of text_general I am using in schema.xml
