Using Search Templates

edit

See Search Template documentation

Define your template parameters as a Map<String,String>:

Map<String, String> template_params = new HashMap<>();
template_params.put("param_gender", "male");

You can use your stored search templates in config/scripts. For example, if you have a file named config/scripts/template_gender.mustache containing:

{
    "template" : {
        "query" : {
            "match" : {
                "gender" : "{{param_gender}}"
            }
        }
    }
}

Execute it with:

SearchResponse sr = client.prepareSearch()
        .setTemplateName("template_gender")
        .setTemplateType(ScriptService.ScriptType.FILE)
        .setTemplateParams(template_params)
        .get();

You can also store your template in a special index named .scripts:

client.preparePutIndexedScript("mustache", "template_gender",
        "{\n" +
        "    \"template\" : {\n" +
        "        \"query\" : {\n" +
        "            \"match\" : {\n" +
        "                \"gender\" : \"{{param_gender}}\"\n" +
        "            }\n" +
        "        }\n" +
        "    }\n" +
        "}").get();

To execute an indexed templates, use ScriptService.ScriptType.INDEXED:

SearchResponse sr = client.prepareSearch()
        .setTemplateName("template_gender")
        .setTemplateType(ScriptService.ScriptType.INDEXED)
        .setTemplateParams(template_params)
        .get();
