Subject [jira] [Commented] (SOLR-9526) data_driven configs defaults to "strings" for unmapped fields, makes most fields containing "textual content" unsearchable, breaks tutorial examples

Jan Høydahl commented on SOLR-9526:
-----------------------------------

I have recorded a Terminal session recording to show how this patch works, from creating a
collection, to adding a doc, inspecting schema and verifying that the string copy is cutoff.
Enjoy:

[~arafalov] Don't you agree that this approach is better than having some field copying being
done in URP and some in schema? You can now:
# Create a collection
# Define some fields up-front with schema REST API
# Start indexing documents and let other fields be guessed, searchable and facetable (_str)
# Inspect the schema created, and if you're happy you can switch to {{update.autoCreateFields=false}}
or even copy the schema to another collection
# If you're not happy with some field guessing, you can modify schema with the API, changing
type, removing/adding {{*_str}} copyField rules etc
# You can even create a {{typeMapping}} in the {{add-unknown-fields-to-the-schema}} chain
that will copy all Integers to a {{_f}} float version or any other combination if it makes
sense for you :)

> James Pritchett pointed out on the solr-user list that this sample query from the quick
start tutorial matched no docs (even though the tutorial text says "The above request returns
only one document")...
> http://localhost:8983/solr/gettingstarted/select?wt=json&indent=true&q=name:foundation
> The root problem seems to be that the add-unknown-fields-to-the-schema chain in data_driven_schema_configs
is configured with...
> {code}
> <str name="defaultFieldType">strings</str>
> {code}
> ...and the "strings" type uses StrField and is not tokenized.
