I just bumped into "more like this" functionality/api. Is there a
possibility to combine the result from more_like_this with some additional
search constraint?
I have two following ES query which works:
POST /h/B/_search
{
"query":{
"more_like_this" : {
"fields" : ["desc"],
"ids" : ["511111260"],
"min_term_freq" : 1,
"max_query_terms" : 25
}
}
}
Which returns
{
"took": 16,
"timed_out": false,
"_shards": {
"total": 3,
"successful": 3,
"failed": 0
},
"hits": {
"total": 53,
"max_score": 3.2860293,
"hits": [
....
Which is fine but I need to specify additional constraint over other field
of the underlying document which works separately fine:
POST /h/B/_search
{
"query":{
"bool" : {
"must" : {
"match" : { "Kind" : "Pen" }
}
}
}
}
I would love to combine those two to one, as the query should state: "Find
a similar items to items labeled with Pen". I tried following with nested
query but that gives me some error back:
POST /h/B/_search
{
"query":{
"more_like_this" : {
"fields" : ["desc"],
"ids" : ["511111260"],
"min_term_freq" : 1,
"max_query_terms" : 25
},
"nested":{
"query":{
"bool" : {
"must" : {
"match" : { "Kind" : "Pen" }
}
}
}
}
}
}
I tried several variant for combining those two search criteria but so far
with no luck. If someone more experienced could provide some hint that
would be really appreciated.
Thanks for helping me out
