RegEx on CommonCrawl API filter parameter

Get offset and length of a subset of a WAT archive from Common Crawl index server

QUESTION

RegEx on CommonCrawl API filter parameter

Asked 2017-Oct-11 at 10:11

I'm trying to use a regex in the filter parameter but I can't use the $ to determine the end of a string:

My request URL:

http://index.commoncrawl.org/CC-MAIN-2017-39-index?url=*.com/&matchtype=domain&fl=url&filter=~url:.com/$

my filter is using the ~ which makes it a regex
validates correctly on a python regex tester: https://pythex.org/ for any .com URL, just TLD, eg: https://stackoverflow.com/

API documentation: https://github.com/ikreymer/pywb/wiki/CDX-Server-API#api-reference

I'm basically getting a lot of results with pages on each website which I don't care about, I just want the TLD. If I take the $ out it works.

This query should work: http://index.commoncrawl.org/CC-MAIN-2017-39-index?url=*.com/&fl=url&filter=url:.*\.com/$

But in the future you may have to use http://index.commoncrawl.org/CC-MAIN-2017-39-index?url=*.com/&fl=url&filter=~url:.*\.com/$

there is a known bug in pywb #249. It's hopefully fixed and deployed to index.commoncrawl.org soon. As a temporary work-around: use = for regex filters and =~ for "contains" filters.
matchType=domain is not required here as the URL is already matched by an wildcard pattern *.com/. It's supposed to query domain names, e.g. http://index.commoncrawl.org/CC-MAIN-2017-39-index?url=commoncrawl.org&matchType=domain&fl=url.
the regex is matched from the beginning of the field value, so it should be .*\.com/$. See the improved documentation in pywb#250.

QUESTION

Get offset and length of a subset of a WAT archive from Common Crawl index server

Asked 2017-Sep-11 at 09:51

I would like to download a subset of a WAT archive segment from Amazon S3.

Background:

Searching the Common Crawl index at http://index.commoncrawl.org yields results with information about the location of WARC files on AWS S3. For example, searching for url=www.celebuzz.com/2017-01-04/*&output=json yields JSON-formatted results, one of which is

{ "urlkey":"com,celebuzz)/2017-01-04/watch-james-corden-george-michael-tribute", ... "filename":"crawl-data/CC-MAIN-2017-34/segments/1502886104631.25/warc/CC-MAIN-20170818082911-20170818102911-00023.warc.gz", ... "offset":"504411150", "length":"14169", ... }

The filename entry indicates which archive segment contains the WARC file for this particular page. This archive file is huge; but fortunately the entry also contains offset and length fields, which can be used to request the range of bytes containing the relevant subset of the archive segment (see, e.g., lines 22-30 in this gist).

My question:

Given the location of a WARC file segment, I know how to construct the name of the corresponding WAT archive segment (see, e.g., this tutorial). I only need a subset of the WAT file, so I would like to request a range of bytes. But how do I find the corresponding offset and length for the WAT archive segment?

I have checked the API documentation for the Common Crawl index server, and it isn't clear to me that this is even possible. But in case it is, I'm posting this question.

After many trial and error I had managed to get a range from a warc file in python and boto3 the following way:
