You can define URLs as start points for Web page crawling and start crawling here.
"Crawling" means that YaCy will download the given website, extract all links in it and then download the content behind these links.
This is repeated as long as specified under "Crawling Depth".
A crawl can also be started using wget and the < a href = "http://www.yacy-websuche.de/wiki/index.php/Dev:API#Managing_crawl_jobs" > post arguments< / a > for this web page.

Each of these URLs are the root for a crawl start, existing start URLs are always re-loaded.
Other already visited URLs are sorted out as "double", if they are not allowed using the re-crawl option.

This defines how often the Crawler will follow links (of links..) embedded in websites.
0 means that only the page you enter under "Starting Point" will be added
to the index. 2-4 is good for normal indexing. Values over 8 are not useful, since a depth-8 crawl will
index approximately 25.600.000.000 pages, maybe this is the whole WWW.

You can limit the maximum number of pages that are fetched and indexed from a single domain with this option.
You can combine this limitation with the 'Auto-Dom-Filter', so that the limit is applied to all the domains within
the given depth. Domains outside the given depth are then sorted-out anyway.

A questionmark is usually a hint for a dynamic page. URLs pointing to dynamic content should usually not be crawled.
However, there are sometimes web pages with static content that
is accessed with URLs containing question marks. If you are unsure, do not check this to avoid crawl loops.

The filter is a < b > < a href = "http://download.oracle.com/javase/6/docs/api/java/util/regex/Pattern.html" > regular expression< / a > < / b > .
Example: to allow only urls that contain the word 'science', set the must-match filter to '.*science.*'.
You can also use an automatic domain-restriction to fully crawl a single domain.

Crawls can be restricted to specific countries. This uses the country code that can be computed from
the IP of the server that hosts the page. The filter is not a regular expressions but a list of country codes, separated by comma.

After a crawl was done in the past, document may become stale and eventually they are also deleted on the target host.
To remove old files from the search index it is not sufficient to just consider them for re-load but it may be necessary
to delete them because they simply do not exist any more. Use this in combination with re-crawl while this time should be longer.

A web crawl performs a double-check on all links found in the internet against the internal database. If the same url is found again,
then the url is treated as double when you check the 'no doubles' option. A url may be loaded again when it has reached a specific age,
to use that check the 're-load' option.

If checked, the crawler will contact other peers and use them as remote indexers for your crawl.
If you need your crawling results locally, you should switch this off.
