You can think of a query as a question, written in a way Elasticsearch understands. Depending on your data, you can use a query to get answers to questions like:
- What pages on my website contain a specific word or phrase?
- What processes on my server take longer than 500 milliseconds to respond?
What users on my network ran
regsvr32.exewithin the last week?
- How many of my products have a price greater than $20?
A search consists of one or more queries that are combined and sent to Elasticsearch. Documents that match a search’s queries are returned in the hits, or search results, of the response.
A search may also contain additional information used to better process its queries. For example, a search may be limited to a specific index or only return a specific number of results.
