# WordDBInfo(3)

inverted index usage environment.

## NAME

WordDBInfo - inverted index usage environment.

## SYNOPSIS

```
Only called thru WordContext::Initialize()
```

## DESCRIPTION

The inverted indexes may be shared among processes/threads and provide the appropriate locking to prevent mistakes. In addition the memory cache used by *WordList* objects may be shared by processes/threads,  greatly reducing the memory needs in multi-process applications. For more information about the shared environment, check the Berkeley DB documentation.

## CONFIGURATION

For more information on the configuration attributes and a complete list of attributes, see the [mifluz(3)](/mifluz/3.md) manual page.

- **wordlist\_env\_skip {true,false} (default false)**

  If true no environment is created at all. This must never  be used if a *WordList* object is created. It may be useful if only *WordKey* objects are used, for instance.

- **wordlist\_env\_share {true,false} (default false)**

  If true a sharable environment is open or created if none exist.

- **wordlist\_env\_dir \<directory\> (default .)**

  Only valid if *wordlist\_env\_share* set to *true.* Specify the directory in which the sharable environment will  be created. All inverted indexes specified with a non-absolute pathname will be created relative to this directory.
