Note: We are no longer working on
Version 4.2, as development have moved on to Version
6.0, but you can download the final 4.2 release (Build 1013)
here and get the Users
Guide for this version here.
This is purely for supporting users of the previous version. We
recommend upgrading to Version 6.0 where
possible, as we have improved many aspects of Zoom and have addressed
many issues based on user feedback.

when followed by a space.

- Fixed "Help" button for Synonyms tab
in the Configuration window.
- Fixed crash bug in CGI search when using spelling
- Updated ASP script to avoid variable names conflicting
with other scripts if you are embedding search.asp in other ASP
version. This allows the Russian/Cyrillic workaround with UTF-8
parameter decoding to work correctly.
Version 4.2.1000 (17
- Synonyms: This feature allows
you to specify synonyms, variations of words, common misspellings,
etc. and allow you to map them to an equivalent word in the index.
This can be very helpful if many users on your site are searching
for names which are different to the ones you used on your website,
but have the same meaning. For example, the word "question"
could be made equivalent to "inquiry,enquiry,query,questions",
so that when a user searches for any of the aforementioned words,
they would get the same results.
- Exclusion/negative searches:
This allows your users to perform search queries which exclude
a certain keyword by preceding the search term with a hyphen (eg.
"cats -dog" would return all pages containing the word
"cat" but not the word "dog").
- Improved spelling suggestions: We have improved
the spelling suggestions algorithm to provide more accurate and
useful suggestions when a user's search returns few results. It
will also return multiple suggestions for single word searches.

yuml, and more.

description or title but the individual words of the phrase can
be found in the content of the document.

has different charset" to be shown incorrectly (eg. when
both the template and Indexer is set to use UTF-8).
- Prevents Zoom from remembering Window positions which are outside
the visible area of the desktop.
"Next" links when using UTF-8.
- Fixed bug causing "aaaaa"s to appear in the context
- Fixed bug with some HTML entities in the URL failing to be converted.
- Fixed issue on Windows 98 with plugins causing a DOS window
to appear when processing a file.
- More bug fixes and changes.
(11 Jul 2005)

positions and "show wizard on startup" settings.

Version 4.1.1001 (27
- Fixed ASP search script which was incorrectly
encoding the query in HTML, and causing exact phrase matching
to not work.
- Added detection of non-supported Content-Type
headers, which allow Zoom to ignore download scripts which may
serve binary files such as .exe or images instead of indexing
them as text.
- Added decoding of URL escape characters (eg.
%20) in filenames when they are used as a page title (eg. PDF
files with no meta title information or .desc file).
Version 4.1.1000 (22
Version 4.1 offers many improvements based on user
requested features, further adding to the power of Zoom, while maintaining
the ease of use and search speed inherent in 4.0. With the new weighting
options, it is also now capable of producing more accurate and relevant
search results than ever.
- Automatic "content density"
weighting adjustment: automatically adjusts the weighting
of words found in a file depending on the density of its content.
This helps prevent large files (such as PDF documents with 50+
pages) from always appearing as the most relevant result, and
gives greater priority to smaller documents.
- Weighting options for heading tags: increase or decrease
the importance of text found in <H1> and <H2> tags.
- Weighting options for filenames: increase or decrease
the importance of search text found in filenames.
- Support for ASP.NET: you can now create an ASP.NET (.aspx)
search page to integrate Zoom into your ASP.NET website seamlessly.
Find out more here.
- Determine file types by "content-type"
header: This allows Zoom to index PDF, DOC, and other file
types served by a server-side download script (eg. http://www.mysite.com/getfile.php?fileid=123)

support: allows you to index and search DjVu
- Support "Last-Modified" meta date tag: allows
you to specify date/time for dynamically generated pages easily
for the "Sort by date" option.

spider mode indexing on Intranets to scan and index documents
on the web server as well as the file network.
- Support for multiple category patterns: allows you to
specify multiple patterns for each category to match files by.
- New index log window options: allow you to right click
on a line in the index log and copy the line to the clipboard,
or open the URL in your browser, etc.

you to specify the maximum number of words to index from each

Version 4.0.1000 (9
Zoom Search Engine Version 4.0 introduces many new
features and an overhaul of the indexer internals to provide more
powerful searching options, better performance (indexes larger sites
with the same hardware, and indexes them faster), and improved usability.
- Multi-threaded downloading:
Dramatically improve the speed of spider mode indexing, by
allowing multiple downloads and indexing to occur simultaneously.
- Reduced memory usage: Allows users
to index much larger sites than before, with around 30% less memory
- Sort by date or relevance: Option
to sort search results by date and show file dates.
- Spelling suggestions: Provide
users with spelling suggestions or a similar word which is more
popular, when few results are found.
- Built-in FTP uploading: Zoom can now
upload the search files after indexing, directly to your web server.
No need for an external FTP client, and can be configured to automatically
upload after every index. [screenshot]
- Built-in Zoom Scheduler: You
can now schedule Zoom to automatically index, or generate reports
for your site, directly from Zoom, with a few mouse clicks. [screenshot]
- Step-by-step wizard: an easy-to-follow
guide which helps new users get started setting up the Indexer
for their site. Also useful for more experienced users who just
want to get something up and running as soon as possible. [screenshot]
- Shockwave Flash plugin: Index and search
through Shockwave Flash, and FlashPaper files and support spider
crawling Flash-based sites (it will successfully follow links
from Flash-based navigation menus etc). [plugins
- Frames and IFRAME spider indexing: The spider will now
crawl pages and follow links within frames and IFRAMES.
- Modify or translate search page text: Zoom now allows
you to translate the text generated by the search page (eg. "No
results found", "Search results for....", etc.),
without having to modify the search script. You can translate
your entire search function to a different language, or just customize
the text as you see fit. French and German translation files have
been included with this release.
- More flexible indexing options: Select exactly what you
want to index, from title of page, filename, page content, meta
description, meta keywords and meta author
- More flexible results layout options: Select which element
to display in the search results with a simple check box.
- More boosting features: Give you greater control over
which page gets higher priority in the search results. New ZOOMPAGEBOOST
options allow you to boost a page's importance. Also, more flexible
word boosting (-5 to +5) options for words that appear within
a page title, meta description or keywords.
- Improved international language options: accent characters
will now appear in the context descriptions (in their original
form), even when accent insensitivity is enabled.
- Multiple start points for offline mode
- Multiple base URLs per spider start point: Each start
point can have multiple base URLs which allow links to be considered
"internal". For example, http://www.mysite.com/ can
have both "http://www.mysite.com/" and "http://private.mysite.com/"
be its base URL.
- New statistical report options: List search terms sorted
by popularity, append unique date/time to filenames, and specify
a different folder for reports to be uploaded to.
- Support for retrieving meta information from PDF files (meta
description, document title, document author, etc.)
- Improved template management: Easier to maintain multiple
sites with different search page templates. No longer necessary
to edit the template source file or to make multiple copies. Just
directly modify the search template in the output directory!
- Highlighting now also applies to search result titles.
- Control which messages appear in the Indexer log window. Progress
bars for downloading messages.
- Many other bug fixes and improvements based on users' requests
and beta testers feedback.
