1. The document index (Doc.idx) keeps information about each document.
It is a fixed width ISAM (Index sequential access mode) index, orderd by docID.
The information stored in each entry includes a pointer into the repository,
a document length, a document checksum.
//Doc.idx 鏂囨。緙栧彿 鏂囨。闀垮害 checksum hash鐮?nbsp;

The url index (url.idx) is used to convert URLs into docIDs.
//url.idx

//url.idx end
It is a list of URL checksums with their corresponding docIDs and is sorted by
checksum. In order to find the docID of a particular URL, the URL's checksum
is computed and a binary search is performed on the checksums file to find its
docID.

1. The document index (Doc.idx) keeps information about each document.
It is a fixed width ISAM (Index sequential access mode) index, orderd by docID.
The information stored in each entry includes a pointer into the repository,
a document length, a document checksum.
//Doc.idx 鏂囨。緙栧彿 鏂囨。闀垮害 checksum hash鐮?/p>

The url index (url.idx) is used to convert URLs into docIDs.

//url.idx end
It is a list of URL checksums with their corresponding docIDs and is sorted by
checksum. In order to find the docID of a particular URL, the URL's checksum
is computed and a binary search is performed on the checksums file to find its
docID.
