_Search Condition_
1. Were routing to each user ID.
2. Java Code
FilterBuilder[] reporterFilters = null;
FilterBuilder filters = null;
SearchRequestBuilder builder = client.prepareSearch(index);
builder.setFrom((Integer) params.get("searchFrom"));
builder.setSize((Integer) params.get("searchCnt"));
builder.setTypes(type);
builder.addSort((String) params.get("sortField"), (Boolean)
params.get("ascending") ? SortOrder.ASC : SortOrder.DESC);
//Set date range filter
if (params.get("fromDate") != null) {
filters =
FilterBuilders.rangeFilter("regDate").from(params.get("fromDate")).to(params.get("toDate"));
}
//Set category filter
if (params.get("categoryId") != null) {
filters =
FilterBuilders.andFilter(FilterBuilders.termFilter("categoryId",
params.get("categoryId")), filters);
}
//Set query filter
if (params.get("query") != null) {
builder.setQuery(QueryBuilders
.queryString((String) params.get("query"))
.field("title")
.field("summary")
.field("content")
.defaultOperator(QueryStringQueryBuilder.Operator.AND)
.analyzer("cjk")
.useDisMax(true)
);
}
builder.setFilter(filters);
SearchResponse response = builder
.execute()
.actionGet();
\*Current caching before, it takes about 2-4 seconds.
I would like to receive a response within one second.
What can I do?

_Thanks in advance for your answer._
