# /members/\{member\}/search/predicate \[GET\]

## Description

Search all member’s groups by predicate.

This service does the same as the group search but collates the results from multiple groups.

### The indexes

The current implementation of PageSeeder produces one Lucene index per group.

This service searches all the member’s groups. To narrow the target groups, use the groups parameter with a comma-separated list of group names.

### The query

The parameters used for a predicate query are predicate and defaultfield. The predicate specified must be parseable by the Lucene classic parser. See [http://lucene.apache.org/core/5\_2\_1/queryparser/org/apache/lucene/queryparser/classic/package-summary.html](http://lucene.apache.org/core/5_2_1/queryparser/org/apache/lucene/queryparser/classic/package-summary.html) for more info.

For details see [Service: /groups/\{group\}/search \[GET\]](group-search-GET.md).

> **Warning:** The predicate specification might change with different Lucene versions so this service should not be used for production systems.

> **Note:** The service returns an error if any of the following fields are in the parameters because they could be defined differently in different project catalogs: `psproperty-*, psmetadata-*, psinline-, psblock-`.

## Parameters

| Name | Description | Required | Type | Default |
| --- | --- | --- | --- | --- |
| defaultfield | The default field, only used with the predicate parameter | no | string | `pscontent` |
| facets | A comma-separated list of fields to use as facets | no | strings |  |
| facetsize | The max number of facet values to load (max 1000) | no | integer | `10` |
| fieldsize | Maximum number of characters allowed in a result field (max 10000) | no | integer | `1000` |
| groups | A comma-separated list of group names (only used when there is a project on the request) | no | strings |  |
| page | The current page to view | no | integer | `1` |
| pagesize | How many results does a page contain | no | integer | `100` |
| predicate | The lucene predicate, takes precedence over the question parameter | no | string |  |
| sortfields | A comma-separated list of fields to sort the results | no | strings |  |

## Permission

Only the member themselves, or an administrator, can invoke this service.

| 0x1505 | If the facet size specified is bigger than the global property for face size ( maxFacetSize) |
| 0x1506 | If a numeric field is specified as a facet |
