It will execute a textual search in Elasticsearch per the flag you provide, either searching for a single word (single filter) OR searching for multiple words (multiple filters), OR without any filter, which is basically a match_all query. We also added SSTable Index Caching (4.6). This held true whether the measurement was of throughputs, P99 latencies, or conducting administrative tasks such as replacing a node or doubling a cluster size. Additional benefits of full text search is the ability to retrieve multiple results sorted by their relevance. Peter Corless is the Director of Technical Advocacy at ScyllaDB.
