Querying/filtering for a single term
Searching or filtering for a particular term is frequently done. A term query and filter work with exact values and are generally very fast.
The term query/filter can be compared to the equals "=" query in the SQL world (for the fields that are not tokenized).
Getting ready
You need a working ElasticSearch cluster and an index populated with the script chapter_05/populate_query.sh, available in the code bundle for this book.
How to do it...
In order to execute a term query/filter, perform the following steps:
Execute a term query from the command line:
curl -XPOST 'http://127.0.0.1:9200/test-index/test-type/_search?pretty=true' -d '{ "query": { "term": { "uuid": "33333" } } }'
The following result should be returned by ElasticSearch if everything works all right:
{ "took" : 58, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 1, "max_score" : 0.30685282, ...
