Re: How to query against dynamic fields without listing them all?
The other options is to use query field alias:
https://lucene.apache.org/solr/guide/8_1/the-extended-dismax-query-parser.html#field-aliasing-using-per-field-qf-overrides
(example:
https://github.com/arafalov/solr-indexing-book/blob/master/published/languages/conf/solrconfig.xml#L20
). This still does not allow wildcards (I think, check!), but at least
it allows to isolate field names as a reference in a separate
variable.
And you can update that variable using Request Parameter API:
https://lucene.apache.org/solr/guide/8_1/request-parameters-api.html#request-parameters-api
You can periodically get the list of all fields, using Luke endpoint.
I don't remember if/where it is documented, but you can examine the
traffic between Admin UI (Analysis or Schema screen) and backend to
see how it works.
You may even have a custom postCommit listener defined that could
check the current list of dynamic fields and write appropriate
mapping:
https://lucene.apache.org/solr/guide/8_1/updatehandlers-in-solrconfig.html#event-listeners

Alex.
P.s. If you use copyField and the target does not store content, just
index - then the overhead is not too bad. And if your original fields
are store-only (because they are never searched directly) and the
copyField target is index-only, then there is no extra overhead.

Thanks David. Yes, I see that would work, but wouldn't that increase my
index size? It would be best if Solr supported dynamic field in "qf".

Re: How to query against dynamic fields without listing them all?
Hi Steven,
You can dump all the dynamic fields into a copyField
Then you can just set
"qf":"CC_COMP_NAME_ALL"

indexed, it is just that Solr not paying attention to the dynamic field

I don't want to keep a list of those dynamic fields and pass them to my

those dynamic fields from Solr so that I don't have to maintain and sync-up

How to query against dynamic fields without listing them all?
Hi everyone,
In my schema, I have the following field:
When I index, I create dynamic fields and index into it like so:
doc.addField("CC_COMP_NAME_" + componentName.toUpperCase(),
ccAllFieldsDataValue);
In my query handler, I have this:
{"requestHandler":{"/select_hcl":{
"class":"solr.SearchHandler",
"name":"/select_hcl",
"defaults":{
"defType":"edismax",
"echoParams":"explicit",
"fl":"CC_UNIQUE_FIELD,CC_FILE_PATH,score",
"indent":"true",
"qf":"CC_COMP_NAME_*",
"rows":"100",
"wt":"xml"
My expectation was when i query using this handler, it will include all the
dynamic fields with the prefix of "CC_COMP_NAME_" however, that is not
happening and I'm getting 0 hits. But when I use the full field name, such
as CC_COMP_NAME_1 or CC_COMP_NAME_2, that works so I know my data is
indexed, it is just that Solr not paying attention to the dynamic field
syntax in "qf".
I don't want to keep a list of those dynamic fields and pass them to my
handler, but if I must, than I must. If so, how can I get the list of
those dynamic fields from Solr so that I don't have to maintain and sync-up
the list myself.
Thanks
Steven
