Re: Query Partial Matching on auto schema

[Guilleret Florian <gu...@gmail.com>]

Thanks you for your answer.

So i saw that in solrconfig.xml i got :

  <schemaFactory class="ManagedIndexSchemaFactory">
    <bool name="mutable">true</bool>
    <str name="managedSchemaResourceName">managed-schema</str>
  </schemaFactory>


And in file managed-schema i got all the schema :

<!-- Solr managed schema - automatically generated - DO NOT EDIT -->


But solr tell to not edit the managed-schema. So where do i need to put
this :

<analyzer>
  <tokenizer class="solr.StandardTokenizerFactory"/>
  <filter class="solr.EdgeNGramFilterFactory"/></analyzer>


 ?

Re: Query Partial Matching on auto schema

[Erick Erickson <er...@gmail.com>]

You can
1> use the "managed schema API", see:
https://lucene.apache.org/solr/guide/6_6/schema-api.html#schema-api
or
2> switch to "classic schema", see:
https://lucene.apache.org/solr/guide/6_6/schema-factory-definition-in-solrconfig.html
or
3> You can actually edit that file if you do it offline. The problem
is that if you do hand-edits _and_ use the managed schema to
programmatically change the file your hand-edits will be overwritten.
Safest is to shut all your solr nodes down, hand edit the schema file,
and then start them all backup.

Best,
Erick
