Hi All:
I am looking into providing a phrase suggester/ inline completion
feature for search. I have been looking at the features as provided in
Elasticsearch. However, I have not been able to understand the following :
1. Term/Phrase suggesters - Are these features search time features and
How does mapping of content play into this feature ?
2. Auto Completion - I think I a working example :
(sample mapping provided :
"Titles": {
"properties": {
"DOC_ID": {
"type":"string"
},
"TITLE": {
"type": "string"
},
"TITLE_suggest" : {
"type" : "completion",
"index_analyzer" : "simple",
"search_analyzer" : "simple",
"payloads" : true
}
}
}
)
For content indexed , I am able to execute requests like the following : :
curl -XPOST http:/host:920/index/_suggest -d
'{"Titles":{"text":"on","completion":{"field":"TITLE_suggest"}}}'
and I get back suggestions. But only those that start with the phrase "on".
{"_shards":{"total":5,"successful":5,"failed":0},"Titles":[{"text":"on","offset":0,"length":2,"options":[{"text":"'Once
Upon A Time...' tells a torrid tale of forbidden love and eventual
betrayal","score":1.0},{"text":"On Drill Program
Progress<DRK.V>","score":1.0},{"text":"On Foreign
Shores","score":1.0},{"text":"On golden pond: Back to back Olympic
champs","score":1.0},{"text":"Once Upon A Time In Mumbaai Dobaara fails to
impress critics","score":1.0}]}]}
However, What I want to get is, where the phrase" on" appears in the title,
as part of a term or a phrase. How would I tweak my request or making to
be able to get that ?
Thanks much
Ramdev
