-----------------------------------
Summary: LTR FieldLengthFeature cannot cope with documents that do
not have the requested field
Key: SOLR-13219
URL: https://issues.apache.org/jira/browse/SOLR-13219
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - LTR
Affects Versions: 7.6
Environment: OSX - Mojave
Reporter: Nick Veenhof
1) Create an index with a dynamic field, eg tm_my_fulltext_field based on tm_*
dynamic field
2) Index your documents and make sure not all of the documents have the
tm_my_fulltext_field field.
3) Set up a feature store as follows
{code:java}
{
"initArgs": {},
"initializedOn": "2019-01-21T21:09:59.011Z",
"updatedSinceInit": "2019-01-21T22:01:14.113Z",
"managedList": [
{
"name": "descriptionLength",
"class": "org.apache.solr.ltr.feature.FieldLengthFeature",
"params": {
"field": "tm_my_fulltext_field"
},
"store": "_DEFAULT_"
}
]
}
{code}
Try to fetch the feature in a query
{code:java}
http://localhost:8983/solr/dropsolid8/select?q=europe&json.nl=flat&omitHeader=true&fl=ss_search_api_id,ss_search_api_language,hash,[features]&start=0&rows=10&wt=json&rq={!ltr
efi.query=europe model=originalScoreModel}}&df=tm_X3b_nl_rendered_item
{code}
You'll see
