To start with, let us remind that using PacketAI, your logs are stored as JSON documents. Those documents have various fields, the most important one being the `message` field. This field is automatically parsed from incoming log lines, wether they have a native JSON format or not. This being said, the PacketAI search engine supports various types of search queries: * Plain text search * Key:value search * Regexp search * Boolean search ### Plain text search This is the simplest search available, that let users search the `message` field of each log line/message. If you want to search other JSON fields, you should check the `key:value` search.

Plain text search for "latency" will search the `message` field of log lines

### Key:value search This mode lets you perform field-level searches (remember each log line is stored as a JSON document).

Key:value search for key `fields.agentID`

### Regexp search This mode is for fine-grained string search and requires a knowledge of how a regexp works. First, switch from *Simple Query* to *Regexp Query* using the switch menu at the right-hand side of the search bar. Then proceed to search using your regexp. * Please refer to the official documentation about [Regexp expression syntax](https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html).

### Boolean search This search mode lets you combine any of the above searches using the AND and OR operators.
