|
|
<p>YaCy has a large number of document parsers included.</p><br><br>
|
|
|
|
|
|
|
|
|
|
<p><img width="480" src="grafics/YaCy_Technology_IndexDistribution.png" align="center"></p>
|
|
|
|
|
<p>When YaCy has indexed a number of web pages, it starts to distribute parts of the web index
|
|
|
|
|
to other YaCy peers. That causes that all indexes that users of YaCy generate are mixed with each other.
|
|
|
|
|
The indexes are stored to such peers that they can be found efficiently again.</p><br><br>
|
|
|
|
|
|
|
|
|
|
<p><img width="480" src="grafics/YaCy_Technology_IndexSearch.png" align="center"></p>
|
|
|
|
|
<p>When a web search in you local peer is done, it searches not only the own database, but also
|
|
|
|
|
databases of other YaCy peers. Only those peers are searched that should have the specific index.</p><br><br>
|

|
|
|
|
|
<p>The workflow inside YaCy. There is no user action required for steering of the workflow,
|
|
|
|
|
but the user interface offers a large number of monitoring pages that show status information about the queues and stacks.</p>
