DESCRIPTION
estwaver is an aggregation of sub commands. The name of a sub command is specified by the
first argument. Other arguments are parsed according to each sub command. The argument
rootdir specifies the crawler root directory which contains configuration file and so on.
estwaver init [-apn|-acc] [-xs|-xl|-xh] [-sv|-si|-sa] rootdir
Create the crawler root directory.
If -apn is specified, N-gram analysis is performed against European text also.
If -acc is specified, character category analysis is performed instead of N-gram
analysis.
If -xs is specified, the index is tuned to register less than 50000 documents.
If -xl is specified, the index is tuned to register more than 300000 documents.
If -xh is specified, the index is tuned to register more than 1000000 documents.
If -sv is specified, scores are stored as void.
If -si is specified, scores are stored as 32-bit integer.
If -sa is specified, scores are stored as-is and marked not to be tuned when
search.
estwaver crawl [-restart|-revisit|-revcont] rootdir
Start crawling.
If -restart is specified, crawling is restarted from the seed documents.
If -revisit is specified, collected documents are revisited.
If -revcont is specified, collected documents are revisited and then crawling is
continued.</dd>
estwaver unittest rootdir
Perform unit tests.
estwaver fetch [-proxy hostr port] [-tout num] [-il lang] url
Fetch a document.
url specifies the URL of a document.
-proxy specifies the host name and the port number of the proxy server.
-tout specifies timeout in seconds.
-il specifies the preferred language. By default, it is English.
All sub commands return 0 if the operation is success, else return 1. A running crawler
finishes with closing the database when it catches the signal 1 (SIGHUP), 2 (SIGINT), 3
(SIGQUIT), or 15 (SIGTERM).
When crawling finishes, there is a directory _index in the crawler root directory. It is
an index available by estcmd and so on.
