This guide is intended for those upgrading from 3.1.x or earlier versions to 3.2.x. The best advice is don't. That is, it is highly recommended that you install the 3.2 release in a separate directory tree and treat everything as if you were installing it for the first time. This is not just because this is a beta release. There are two main reasons for this:

• The default directory structure of this release is different from previous releases, more in line with other UNIX programs.
• The databases are all in different formats. This version cannot read databases from previous versions since the new formats have significantly more information and this cannot be reconstructed from old databases. This goes for fuzzy databases as well.

Additionally, you may find things a bit rough at first. We appreciate your comments and suggestions, especially in the form of performance comparisons with the 3.1.x releases. Additionally, there are several things planned for the final 3.2.0 release that have not been implemented yet:

• Proximity (near) searching.
• Phrase searching method (in addition to and, or, and boolean).
• Field-based searching--restricting to a header, title, etc.
• Date-based searching--restricting to a range of dates.
• Implementation of a more accurate scoring system.
• Parallel indexing and searching.
• "Collections" of multiple databases.
• Support for nntp: and ftp: access
• Detection of loops and/or duplicate documents
• An accent-based fuzzy algorithm: match résumé with resume.
