Hi, I have an existing mapping with me but I'm not able to understand it fully. curl -XPUT '[http://localhost:9200/auto\_index/](http://localhost:9200/auto_index/)[http://localhost:9200/acqindex/](http://localhost:9200/acqindex/)' -d '{ "settings" : { "index" : { "number\_of\_shards" : 1, "number\_of\_replicas" : 1, "analysis" : { "analyzer" : { "str\_search\_analyzer" : { "tokenizer" : "standard", "filter" : ["lowercase","asciifolding","suggestion\_shingle","edgengram"] }, "str\_index\_analyzer" : { "tokenizer" : "standard", "filter" : ["lowercase","asciifolding","suggestions\_shingle","edgengram"] } }, "filter" : { "suggestions\_shingle": { "type": "shingle", "min\_shingle\_size": 2, "max\_shingle\_size": 5 }, "edgengram" : { "type" : "edgeNGram", "min\_gram" : 2, "max\_gram" : 30, "side" : "front" } } }, "similarity" : { "index": { "type": "default" }, "search": { "type": "default" } } } } curl -XPUT 'localhost:9200/auto\_index/autocomplete/\_mapping' -d '{ "autocomplete":{ "\_boost" : { "name" : "po", "null\_value" : 4.0 }, "properties": { "ad": { "type": "string", "search\_analyzer" : "str\_search\_analyzer", "index\_analyzer" : "str\_index\_analyzer", "omit\_norms": "true", "similarity": "index" }, "category": { "type": "string", "include\_in\_all" : false }, "cn": { "type": "string", "search\_analyzer" : "str\_search\_analyzer", "index\_analyzer" : "str\_index\_analyzer", "omit\_norms": "true", "similarity": "index" }, "ctype": { "type": "string", "search\_analyzer" : "keyword", "index\_analyzer" : "keyword", "omit\_norms": "true", "similarity": "index" }, "eid": { "type": "string", "include\_in\_all" : false }, "st": { "type": "string", "search\_analyzer" : "str\_search\_analyzer", "index\_analyzer" : "str\_index\_analyzer", "omit\_norms": "true", "similarity": "index" }, "co": { "type": "string", "include\_in\_all" : false }, "st": { "type": "string", "search\_analyzer" : "str\_search\_analyzer", "index\_analyzer" : "str\_index\_analyzer", "omit\_norms": "true", "similarity": "index" }, "co": { "type": "string", "search\_analyzer" : "str\_search\_analyzer", "index\_analyzer" : "str\_index\_analyzer", "omit\_norms": "true", "similarity": "index" }, "po": { "type": "double", "boost": 4.0 }, "en":{ "type": "boolean" }, "\_oid":{ "type": "long" }, "text": { "type": "string", "search\_analyzer" : "str\_search\_analyzer", "index\_analyzer" : "str\_index\_analyzer", "omit\_norms": "true", "similarity": "index" }, "url": { "type": "string" } } } }' I'm not able to understand how the index and search analyzer works exactly. Let's say I have following documents with me:- {text:hotels in hosur} {text:hotels in innsburg} {text: hotels in mp} {text: hotels in ink} {text:hotels in ranchi} Now If I query for 'hotels in' then I get hotels in hosur on the top. Is it because I have more occurrences of ho i the doc. Can anyone please explain me with some sample sentence like how exactly my query string is getting analyzed ?

Coder, The best way to understand what an analyzer is doing is by using the \_analyze api. For example if you do something like this: curl -XGET '[http://localhost:9200/auto\_index/\_analyze?analyzer=str\_search\_analyzer&pretty&text=hotels%20in%20hosur](http://localhost:9200/auto_index/_analyze?analyzer=str_search_analyzer&pretty&text=hotels%20in%20hosur)' It will tell you how that text is analyzed. In your mapping, the analyzer does suggestions\_shingle and edgengram. The suggestions\_shingle does the shingle token filter ([http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-shingle-tokenfilter.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-shingle-tokenfilter.html)) so for example: "hotels in hosur" becomes "hotels", "in", "hosur", "hotels in", "hotels in hosur", "in hosur" Then your edgengram does the edge ngram token filter ([http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-edgengram-tokenizer.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-edgengram-tokenizer.html)) so for example: "hotels" becomes "ho", "hot", "hote", etc... "in" becomes "in" "hosur" becomes "ho", "hos", "hosu", etc... etc... -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Binh, I have a doubt in the above explanation. You mentioned that after suggestions\_shingle: "hotels in hosur" becomes "hotels", "in", "hosur", "hotels in", "hotels in hosur", "in hosur" but shouldn't be "hotels" , "in", "hosur" should be removed since my min\_shingle\_size is 2 or is it like the original tokens will stay always. Also, after edgengram-tokenizer I'm getting "ho" many times so in my final output will there be only one "ho" ? or multiple "ho" because by default after every filter "unique" token filter is used by Elasticsearch, please correct me if I'm wrong ? How can I use unique token filter to remove the repeated tokens after final processing ? I tried adding "unique" after "edgengram" but it is not working ?

Coder, 1. For the shingle token filter, there is a property called output\_unigrams which is true by default. What it does is it will output the single tokens: "hotels", "in", etc in addition to the shingle tokens. If you set it to false, it will remove them. 2. Correct, it will output "ho" many times because for each token that comes out of the shingles, it will do a edge ngram on it. I'm not familiar with the unique token filter but I will check and get back to you. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Binh, I have one more doubt regarding matching of index time tokens with query time tokens. Can you please tell me how elasticsearch does this type of matching ? Is it like it only matches the token or it also matches other information like start\_offset, end\_offset, type and position. ?

Also, are there any conditional token filtering can be done in Elasticsearch. Let's say I want some of my documents to be tokenized with a certain set of token filters whereas others to be indexed using some other set of token filters.

Coder, In general, full-text searches match tokens. If you're doing phrase or span queries, it will also look at positions. If you're doing range queries, like date-range, or numeric range, then it will also look at the actual types.

Analysis is done on a per-field basis. I do not believe you can conditionally change the analyzer for a single field depending on the nature of your data.

Binh, I want to use conditional analysis for one set of documents not the single field in those documents.

You'll probably want two different types with different mappings. So for example some documents will go under "[http://localhost:9200/yourdata/typea](http://localhost:9200/yourdata/typea)" and other documents will go under "[http://localhost:9200/yourdata/typeb](http://localhost:9200/yourdata/typeb)". Each one of these types can have its own independent mapping. You can query all your documents using "[http://localhost:9200/yourdata/\_search](http://localhost:9200/yourdata/_search)".
