    <p>I have built a small app in play2 and elasticsearch that will provide my other applications with an autocomplete feature. It is time to move my elasticsearch instance into production. </p> <p><strong>mapping:</strong></p> <pre><code>curl -XPUT 'http://127.0.0.1:9200/auto_complete/?pretty=1' -d ' { "mappings": { "search_word": { "_all": { "enabled": false }, "properties": { "id": { "type": "string" }, "word": { "fields": { "ngrams": { "type": "string", "analyzer": "custom_ngram" }, "full": { "type": "string", "search_analyzer": "custom_full", "index_analyzer": "custom_full" } }, "type": "multi_field" }, "word_type": { "type": "string" } } } }, "settings": { "analysis": { "filter": { "customnGram": { "max_gram": 50, "min_gram": 2, "type": "edgeNGram" } }, "analyzer": { "custom_ngram": { "filter": [ "standard", "lowercase", "customnGram" ], "type": "custom", "tokenizer": "standard" }, "custom_full": { "filter": [ "standard", "lowercase" ], "type": "custom", "tokenizer": "standard" } } } } } ' </code></pre> <p><strong>Some testing data for you:</strong></p> <pre><code>curl -XPOST 'http://127.0.0.1:9200/_bulk?pretty=1' -d ' {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "vvs", "word_type":"STRONG_SEARCH_WORD"} {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "och VVS ab", "word_type":"WEAK_SEARCH_WORD"} {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "vvs och rörjouren", "word_type":"NAME"} {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "vvs &amp; rörjouren", "word_type":"NAME"} {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "rot och vvs", "word_type":"NAME"} {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "vvsjouren", "word_type":"NAME"} {"index" : {"_index" : "auto_complete", "_type" : "search_word"}} {"word" : "vvs-jouren", "word_type":"NAME"} ' </code></pre> <p><strong>A test query for you:</strong></p> <pre><code>curl -XGET 'http://127.0.0.1:9200/auto_complete/search_word/_search?pretty=1' -d ' { "query": { "bool": { "should": [ { "text": { "search_word.ngrams": { "operator": "and", "query": "vvs" } } }, { "text": { "search_word.full": { "boost": 1, "query": "vvs" } } } ] } } } ' </code></pre> <p>I have been running the instance in default mode when testing.

Do you have any tips for me, or for anybody out there that is moving to production?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
