# Search Queries
|
|
A search query returns dimension values that match the search specification.
|
|
|
|
```json
|
|
{
|
|
"queryType": "search",
|
|
"dataSource": "sample_datasource",
|
|
"granularity": "day",
|
|
"searchDimensions": [
|
|
"dim1",
|
|
"dim2"
|
|
],
|
|
"query": {
|
|
"type": "insensitive_contains",
|
|
"value": "Ke"
|
|
},
|
|
"sort" : {
|
|
"type": "lexicographic"
|
|
},
|
|
"intervals": [
|
|
"2013-01-01T00:00:00.000/2013-01-03T00:00:00.000"
|
|
]
|
|
}
|
|
```
|
|
|
|
There are several main parts to a search query:
|
|
|
|
|property|description|required?|
|
|
|--------|-----------|---------|
|
|
|queryType|This String should always be "search"; this is the first thing Druid looks at to figure out how to interpret the query.|yes|
|
|
|dataSource|A String or Object defining the data source to query, very similar to a table in a relational database. See [DataSource](../querying/datasource.html) for more information.|yes|
|
|
|granularity|Defines the granularity of the query. See [Granularities](../querying/granularities.html).|yes|
|
|
|filter|See [Filters](../querying/filters.html).|no|
|
|
|limit| Defines the maximum number per historical node (parsed as int) of search results to return. |no (default to 1000)|
|
|
|intervals|A JSON Object representing ISO-8601 Intervals. This defines the time ranges to run the query over.|yes|
|
|
|searchDimensions|The dimensions to run the search over. Excluding this means the search is run over all dimensions.|no|
|
|
|query|See [SearchQuerySpec](../querying/searchqueryspec.html).|yes|
|
|
|sort|An object specifying how the results of the search should be sorted.<br/>Possible types are "lexicographic" (the default sort), "alphanumeric", "strlen", and "numeric".<br/>See [Sorting Orders](./sorting-orders.html) for more details.|no|
|
|
|context|See [Context](../querying/query-context.html)|no|
|
|
|
|
The format of the result is:
|
|
|
|
```json
|
|
[
|
|
{
|
|
"timestamp": "2012-01-01T00:00:00.000Z",
|
|
"result": [
|
|
{
|
|
"dimension": "dim1",
|
|
"value": "Ke$ha",
|
|
"count": 3
|
|
},
|
|
{
|
|
"dimension": "dim2",
|
|
"value": "Ke$haForPresident",
|
|
"count": 1
|
|
}
|
|
]
|
|
},
|
|
{
|
|
"timestamp": "2012-01-02T00:00:00.000Z",
|
|
"result": [
|
|
{
|
|
"dimension": "dim1",
|
|
"value": "SomethingThatContainsKe",
|
|
"count": 1
|
|
},
|
|
{
|
|
"dimension": "dim2",
|
|
"value": "SomethingElseThatContainsKe",
|
|
"count": 2
|
|
}
|
|
]
|
|
}
|
|
]
