Hi, is there a lagre(ish) example of an indexmapping somewhere in the ES docs? I'm just starting to dip my toes into ES now. I'm asking because it would be great to have a document like that to begin using ES - just like Solr has a large commented solrconfig.xml and schema.xml file that may be used as a startingpoint for setting it up.

Yes, lots of examples (especially not the standard 🙂 would be cool! Maybe it can help you, here are some examples: > > > > [http://www.elasticsearch.org/guide/reference/mapping/core-types.html](http://www.elasticsearch.org/guide/reference/mapping/core-types.html) [http://www.elasticsearch.org/guide/reference/index-modules/analysis/custom-analyzer.html](http://www.elasticsearch.org/guide/reference/index-modules/analysis/custom-analyzer.html) > **[Your Data, Your Search | Elastic](https://www.elastic.co/blog/your-data-your-search)** > > One of the main aspects when working with business data is to try and have all different components in an ever evolving system to understand the same data structure/format (or as close as possible).

Great! Thanks. As I understand it, when you index a document in ES you can either define a fields properties (in the mapping) when creating the index, but also when you index the document, am I correct? What happens if the two field definitions conflict? Regards, Tarjei ---

On the first your question. 1. You define the settings of the index (analyzers, filters, tokenizers) 2. You define the mappings. Here you can specify many options, field name, field type, use an index or not, what fields to use your analyzers (index\_analyzer, search\_analyzer), see the documentation "Mapping -\> Types -\> core". 3. Put your data, example: { "tweet" { "user" : "kimchy" "message" : "This is a tweet!", "postDate" : "2009-11-15T14:12:12", "retweets" : 4, } } The search should work 🙂 On the second your question I don't know, I use ElasticSearch only the third day 🙂 ---

Mappings can be explicitly defined when you create an index, or use the put mapping API. If you don't specify it, then automatic mappings will be created based on the field indexed (for example, if its a number, then it will be indexed as one).
