# Search Queries #### Search Language Queries CybrHawk uses Lucene query syntax for querying alert data. Lucene provides software developers with an easy-to-use toolkit for implementing full-text search capabilities within target systems, or for building a complete full-text search engine. #### Key Matching You can specify fields to search in the query syntax: * where the `status` field contains `active` ``` status:active ``` * where the `title` field contains `quick` or `brown` ``` title:(quick OR brown) ``` * where the `author` field contains the exact phrase `John Smith` ``` author:"John Smith" ``` * where the `first name` field contains `Alice` (note how we need to escape the space with a backslash) ``` first\ name:Alice ``` * where any of the fields `book.title`, `book.content`, or `book.date` contains `quick` or `brown` (note how we need to escape the `*` with a backslash): ``` book.\*:(quick OR brown) ``` * Search for "foo bar" in the title field and "quick fox" in the body field. ``` title:"foo bar" AND body:"quick fox" ``` * Search for either the phrase "foo bar" in the title field AND the phrase "quick fox" in the body field or the word "fox" in the title field. ``` (title:"foo bar" AND body:"quick fox") OR title:fox ``` * Search for the word "foo" and not "bar" in the title field ``` title:foo -title:bar ``` * where the field `title` has any non-null value: ``` _exists_:title ``` #### Wildcard Matching * Search for any word that starts with "foo" in the title field. ``` title:foo* ``` * Search for any word that starts with "foo" and ends with "bar" in the title field. ``` title:foo*bar ``` * Note that Lucene doesn't support using a `*` symbol as the first character of a search. #### Recommend Reading * [Elastic Query DSL Query String Syntax](https://www.elastic.co/guide/en/elasticsearch/reference/8.11/query-dsl-query-string-query.html#query-string-syntax) * [Apache Lucene Query Parser Syntax](https://lucene.apache.org/core/2_9_4/queryparsersyntax.html) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://cybrhawksoc.gitbook.io/cybrhawk-docs/soc-analyst-guide/search-queries.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
