These are components that offer functionality for the [index-service](../services-core/index-service).

## Indexes
|
|
|
|
|
|
|
|
|
|
There are two indexes with accompanying tools for constructing them.
|
|
|
|
|
|
|
|
|
|
* [index-forward](index-forward/) is the `document->word` index containing metadata
|
|
|
|
|
about each word, such as its position.
|
|
|
|
|
* [index-reverse](index-reverse/) is the `word->document` index.
|
|
|
|
|

|
|
|
These indices rely heavily on the [libraries/btree](../libraries/btree) and [libraries/array](../libraries/array) components.
