For fields you want to retrieve, set store to true in mapping. That said, why do you need to disable source?

Some features that come to me: - Reindexing from Elasticsearch itself. - Debugging (what was the source when I indexed?). - Showing results to user. If you did not store the field, you will have to reindex everything. IMHO, you should disable source only if you really need to disable it (real hard disk constraint, very very big source docs...). ## My 2 cents David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 9 mai 2013 à 01:56, vinod eligeti [veligeti999@gmail.com](mailto:veligeti999@gmail.com) a écrit : David, I am also pondering in some of the implementation of setting "store" value for a field, if one sets the store value to "no" for a field and also \_source for a type is disabled.

Historically, Lucene has no concept of source. A field is either indexed, stored or both (neither does not make sense). Indexed fields can be queried/filtered-in and stored fields can be returned as the result document. So to answer your question, if the source is disabled and a field is not stored, then it either should be indexed or simply ignored. Elasticsearch introduced the concept of source. The biggest issue with stored fields is that each field required a read from the index. With source, only one read is required, although the result is much bigger. If you need only a handful of fields, then storing and retrieving those fields is probably more efficient, but you required many fields or all of them, getting the source is more efficient. -- Ivan On Wed, May 8, 2013 at 4:56 PM, vinod eligeti [veligeti999@gmail.com](mailto:veligeti999@gmail.com) wrote: > David, > > I am also pondering in some of the implementation of setting "store" value > for a field, if one sets the store value to "no" for a field and also > \_source for a type is disabled.

Thanks David and Ivan for the explanation. I guess it make sense to store \_source since the log messages which I store are not huge.
