Subject Re: schema.xml & xi:include -> copyField source :'_my_title' is not a glob and doesn't match any explicit field or dynamicField
Date Fri, 15 May 2015 21:13:03 GMT
Hi Clemens,

I forgot that XInclude requires well-formed XML, so schema-common.xml without <schema></schema>
tags won’t work, since it will have multiple root elements.

But instead of XInclude, you can define external entities for files you want to include, and
then include a reference to them where you want the contents to be included.

This worked for me:

——
schema.xml
——
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE schema [ <!ENTITY schema_common SYSTEM "schema-common.incl"> ]>
<schema name="locale_de" version="1.5">
  &schema_common;
</schema>
——

——
schema-common.incl
——
 <uniqueKey>_my_id</uniqueKey>
 <field indexed="true" name="_version_" stored="true" type="long"/>
 <copyField dest="_my_suggest" source="_my_title"/>
 <fields>
   <field indexed="true" multiValued="false" name="_my_id" required="true" stored="true"
type="string"/>
   <field indexed="true" multiValued="false" name="_my_title" required="true"  stored="true"
type="string"/>
   <field indexed="true" multiValued="true" name="_my_suggest" stored="false" type="string"/>

 </fields>
  <types>
   <fieldType class="solr.StrField" name="string" sortMissingLast="true"/>
    <fieldType class="solr.TrieLongField" name="long" positionIncrementGap="0" precisionStep="0"/>
 </types>

Here’s what I get back from curl "http://localhost:8983/solr/mycore/schema?wt=schema.xml&indent=on”:

——
<?xml version="1.0" encoding="UTF-8"?>
<schema name="locale_de" version="1.5">
  <uniqueKey>_my_id</uniqueKey>
  <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
  <fieldType name="string" class="solr.StrField" sortMissingLast="true"/>
  <field name="_my_id" type="string" multiValued="false" indexed="true" required="true"
stored="true"/>
  <field name="_my_suggest" type="string" multiValued="true" indexed="true" stored="false"/>
  <field name="_my_title" type="string" multiValued="false" indexed="true" required="true"
stored="true"/>
  <field name="_version_" type="long" indexed="true" stored="true"/>
  <copyField source="_my_title" dest="_my_suggest"/>
</schema>

> Field declarations are found in the schema using XPath expressions "/schema/fields/field”
and "/schema/field”, which won’t be found, since in your composite schema they’re at
“/schema/schema/fields/field”.  You’re seeing the copyField error because copyField
rules are found via XPath expression “//copyField”: they are found regardless of the containing
structure.

tags from your schema-common.xml.  You won’t be able to use it alone in that case, but if
you need to do that, you could just create another schema file that includes it inside wrapping
<schema></schema> tags.
