MultiMatch with phrase_prefix support for boost?

cyrilforce · April 8, 2014, 12:11pm

Hi,

I have a query as below :

"multi_match" : {
"query" : "happy",
"fields" : [ "DISPLAY_NAME^8", "PERFORMER" ],
"type": "phrase_prefix",
"operator" : "AND"
}

Result return in the following order:
1)
"_score": 2.1704028,
"_source": {
"DISPLAY_NAME": "Happyman",

"_score": 1.4312989,
"_source": {
"DISPLAY_NAME": "Boishakh (Version 1)",
"PERFORMER": "Happy",

"_score": 1.2510761,
"_source": {
"DISPLAY_NAME": "Franzl Im Happysound",
"PERFORMER": "Franzl & Die Psayrer",

"_score": 1.0920545,
"_source": {
"DISPLAY_NAME": "Happy",
"PERFORMER": "Diandra Arjunaidi"

As the result shown why the #4 have lesser score computed as i already
added a boost in the "DISPLAY_NAME^6" field. Is that the boost not working
for multimatch phrase query ?

Turn on the explain feature to see why example 4 is not getting a higher
score.

I suspect it has something to do with the way you are indexing your data.
If you still have issues a gist would help us.

Hi Dan,

I have enabled an analyzer in mapping due to stopword :

"DISPLAY_NAME": {
"type": "string",
"analyzer": "standard"
}

*The query : *

"multi_match" : {
"query" : "happy",
"fields" : [ "DISPLAY_NAME^8", "PERFORMER" ],
"type": "phrase_prefix",
"operator" : "AND"
}

The boost you define in the 'multi_match' query is not being show in the
explain results, so it is not being applied to the score. It should be
displayed in the weight, i.e.

"description": "weight(DISPLAY_NAME^8:happy in 33593) [PerFieldSimilarity],
result of:"

The 'phrase_prefix' type is the issue, if you remove that type the boost
will be applied. So it doesn't look like you can combine 'multi_match'
boosting with the 'phrase_prefix' as the type.

PERFORMER)

Then it returns (in the following order) :

You could use edge ngrams:

Or if you have the correct version of Elasticsearch, you can use the

Hi Dan,

Been trying to use edgengram analyzer but i don't understand why it produce
the result in the following order :

"DISPLAY_NAME": "Happy Talk"
"DISPLAY_NAME": "Happenings",

I suppose the longer the text ("Happy Talk") it should have lower the
scores ?

*The query that i use : *
{ "explain" : true,
"query" : {
"multi_match": {
"query": "hap",
"fields": [ "DISPLAY_NAME.AUTOCOMPLETE^6", "PERFORMER.AUTOCOMPLETE" ]
}
},
"sort" : [{
"_score" : { "order" : "desc"}}]
}

The result :

Turn on the explain feature to see why example 4 is not getting a
higher score.

I suspect it has something to do with the way you are indexing your
data. If you still have issues a gist would help us.

Hi,

I have a query as below :

"multi_match" : {
"query" : "happy",
"fields" : [ "DISPLAY_NAME^8", "PERFORMER" ],
"type": "phrase_prefix",
"operator" : "AND"
}

Result return in the following order:
1)
"_score": 2.1704028,
"_source": {
"DISPLAY_NAME": "Happyman",

"_score": 1.4312989,
"_source": {
"DISPLAY_NAME": "Boishakh (Version 1)",
"PERFORMER": "Happy",

"_score": 1.2510761,
"_source": {
"DISPLAY_NAME": "Franzl Im Happysound",
"PERFORMER": "Franzl & Die Psayrer",

"_score": 1.0920545,
"_source": {
"DISPLAY_NAME": "Happy",
"PERFORMER": "Diandra Arjunaidi"

As the result shown why the #4 have lesser score computed as i
already added a boost in the "DISPLAY_NAME^6" field. Is that the boost not
working for multimatch phrase query ?
