Thanks, token_filter worked. Also, w/o modifying mapping, using script
filter<http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-script-filter.html>query
worked (query below). However, in both cases, ES seems to treat
multi-element array and array element with multiple words as having the
same token count. ie:
1) [ "apples", "oranges] //length=2
2) [ "apples" ] //length=1
3) [ "apples and oranges"] //length =3, even with filter query (why not 1)?
...not an issue in my particular use case since all ingredients are 1-word,
but I would like to understand how to address case #3 above. Write a custom
Tokenizer?
*Script Filter query:*
{
"query" : {
"field": {
"ingredients": "apples"
}
},
"filter": {
"script": {
"script": "doc['ingredients'].values.length == 1"
}
}
}
