Example 1 with QueryCacheKey

use of com.yahoo.prelude.cache.QueryCacheKey in project vespa by vespa-engine.

the class CachingSearcher method search.

public Result search(com.yahoo.search.Query query, Execution execution) {
    if (query.getNoCache()) {
        return execution.search(query);
    }
    QueryCacheKey queryKey = new QueryCacheKey(query);
    Result cachedResult = cache.get(queryKey);
    if (cachedResult != null) {
        cacheHit();
        return cachedResult;
    }
    cacheMiss();
    // Need a copy, as cache hash key later on, maybe.
    Query originalQuery = query.clone();
    Result result = execution.search(query);
    execution.fill(result);
    if (!noCacheWrite(query)) {
        // Because the query member has changed state
        queryKey.setQuery(originalQuery);
        cache.put(queryKey, result);
    }
    return result;
}
