search in docstrings

Search bar offers the following options:

- Term presence. The below example searches for documents that must contain “foo”, might contain “bar” and must not contain “baz”: `+foo bar -baz`
- Wildcards. The below example searches for documents with words beginning with “foo”: `foo*`
- Search in specific fields. The following search matches all objects in "twisted.mail" that matches “search”: `+qname:twisted.mail.* +search`

  Possible fields: 'name', 'qname' (fully qualified name), 'docstring', and 'kind'. Last two fields are only applicable if "search in docstrings" is enabled.

- Fuzzy matches. The following search matches all documents that have a word within 1 edit distance of “foo”: `foo~1`

`class FilteringLogObserver: (source)`

Constructor: `FilteringLogObserver(observer, predicates, negativeObserver)`

Implements interfaces: `twisted.logger.ILogObserver`

View In Hierarchy

`ILogObserver` that wraps another `ILogObserver`, but filters out events based on applying a series of `ILogFilterPredicate`s.

Method | `__call__` | Forward to next observer if predicate allows it.
Method | `__init__` | No summary
Instance Variable | `_negativeObserver` | Undocumented
Instance Variable | `_observer` | Undocumented
Instance Variable | `_shouldLogEvent` | Undocumented

def __call__(self, event: `LogEvent`): (source)
from `twisted.logger.ILogObserver`

Forward to next observer if predicate allows it.

def __init__(self, observer: `ILogObserver`, predicates: `Iterable[ILogFilterPredicate]`, negativeObserver: `ILogObserver` = bitbucketLogObserver): (source)

Parameters
observer:`ILogObserver` | An observer to which this observer will forward events when `predictates` yield a positive result.
predicates:`Iterable[ILogFilterPredicate]` | Predicates to apply to events before forwarding to the wrapped observer.
negativeObserver:`ILogObserver` | An observer to which this observer will forward events when `predictates` yield a negative result.
