I'm using elasticsearch and am having a devil of a time getting an exact match to happen. I've tried various combinations of match, query_string, etc, and I either get nothing or bad results. Query looks like this:
{
"filter": {
"term": {
"term": "dog",
"type": "main"
}
},
"query": {
"match_phrase": {
"term": "Dog"
}
},
"sort": [
"_score"
]
}
Sorted results
10.102211 {u'term': u'The Dog', u'type': u'main', u'conceptid': 7730506}
10.102211 {u'term': u'That Dog', u'type': u'main', u'conceptid': 4345664}
10.102211 {u'term': u'Dog', u'type': u'main', u'conceptid': 144}
7.147442 {u'term': u'Dog Eat Dog (song)', u'type': u'main', u'conceptid': u'5288184'}
I see, of course that "The Dog", "That Dog" and "Dog" all have the same score, but I need to figure out how I can boost the exact match "Dog" in score.
I also tried
{
"sort": [
"_score"
],
"query": {
"bool": {
"must": [
{
"match": {
"term": "Dog"
}
},
{
"match_phrase": {
"term": {
"query": "Dog",
"boost": 5
}
}
}
]
}
},
"filter": {
"term": {
"term": "dog",
"type": "main"
}
}
}
but that still just gives me
11.887239 {u'term': u'The Dog', u'type': u'main', u'conceptid': 7730506}
11.887239 {u'term': u'That Dog', u'type': u'main', u'conceptid': 4345664}
11.887239 {u'term': u'Dog', u'type': u'main', u'conceptid': 144}
8.410372 {u'term': u'Dog Eat Dog (song)', u'type': u'main', u'conceptid': u'5288184'}
If you want to be able to easily match only ":feed:" inside the message field you might want to costumize an analyzer which doesn't tokenize ":" so you will be able to query the field with a simple "match" query instead of wild characters.
The match query is the standard query for performing a full-text search, including options for fuzzy matching.
Match phrase queryeditA phrase query matches terms up to a configurable slop (which defaults to 0) in any order. Transposed terms have a slop of 2. The analyzer can be set to control which analyzer will perform the analysis process on the text.
The term query finds documents that contain the exact term specified in the inverted index. For instance: POST _search { "query": { "term" : { "user" : "Kimchy" } } } Finds documents which contain the exact term Kimchy in the inverted index of the user field.
Fields are analyzed with the standard analyzer by default. If you would like to check exact match, you could store your field not analyzed also e.g:
"dog":{
"type":"multi_field",
"fields":{
"dog":{
"include_in_all":false,
"type":"string",
"index":"not_analyzed",
"store":"no"
},
"_tokenized":{
"include_in_all":false,
"type":"string",
"index":"analyzed",
"store":"no"
}
}
}
Then you can query the dog-field for exact matches, and dog._tokenized for analyzed queries (like fulltext)
