Zoom allows you to perform incremental indexing so that you can update, add pages, and make changes to an existing set of index files without having to perform a full re-index. This can be particularly useful for large sites (or an index of a large number of sites) where there may be minor incremental changes that require updates to the index, but would be too time consuming (or bandwidth consuming) to re-index the entire site using Spider mode on a regular basis.
Requirements
1. | Incremental indexing is only available for the PHP, ASP, ASP.NET, and CGI platforms. It is not available for the Javascript version since it is incapable of indexing a large enough set of files where incremental indexing would be beneficial. |
2. | In order to use incremental indexing, you must NOT have modified your indexing configuration since the last index was made. The ZCFG file must contain the exact same settings, and the index files must still be in the output folder specified. |
3. | "Updating an existing index" is only available in Spider Mode. It is not available in Offline Mode. Offline mode indexing does not use any Internet traffic and it is many times quicker than spider mode, so this should not be necessary and we would recommend a full re-index for offline mode users. |
Incremental indexing options
The following options are available from the "Index" menu, by selecting "Incremental indexing":
Updating an existing index
