Free image search engines software for linux

Magellan Metasearch is a modular meta search engine, enabling users to monitor as many search engines as they want.
Magellan Metasearch provides a complex query language with standard boolean operators, meta-operators (to search through pages metadata), and proximity operators.
This language enables users to perform far more complex queries than what common search engines currently support. It can be fed any custom sources, since its abstraction layer manages the search results and their meta tags in a uniform way.
In conjunction with the local process scheduler (such as "cron"), Magellan enables you to save your requests and replay them later automatically; new results are sent through email and RSS in realtime. Magellan also provides full anonymity through smart multi-proxy support.
Enhancements:
- This release enhances the automated parsing mechanism ; it also fixes a problem with small result sets that occasionally couldnt be extracted.
- Moreover, new virtual sources are automatically tested on creation / update to check their validity.

ImageServer is a software for maintaining archives of images. Theres much software available to manually view, categorize and search images. ImageServer was designed to solve a different problem:
Imagine being a photographer or photo agency: You have a lot of images in many formats, all stored in a directory structure - your archive.
This creates at least two problems:
- The archive may contain different images with the same name. What do you do when a customer orders "flowers.tif" and this name exists in twenty different subfolders in your archive?
- The customer doesnt need your original 22megapixel 16-bit tiff file for his powerpoint presentation or layouting, he wants a small jpeg instead.
The first problem can be managed by assigning unique names to images every time an image is put into the archive.
The second problem is a little more difficult. Youll have to convert the requested images to smaller JPEGs. After doing that for too many times, you start caching the small JPEGs so you wont have to convert again for the next customer asking for that image. But then, you edit the original image and forget to update the JPEGs. Furthermore, its not enough to keep these resized jpegs for presentations, your customers graphics department also wants correctly downsampled eps images for layouting advertisements in QuarkXPress. So you start having two slaveArchives - one with JPEG and one with EPS images - and spend half of your day trying to synchronize the three.
ImageServer solves both problems automatically. It is a program with a nice GUI, configured to watch your masterArchive. As soon as images are put into any subfolder, theyll be assigned unique names if necessary. Afterwards, each image is read, and for each defined slaveArchive, a preview is created and saved. The same happens when an image in the masterArchive is altered. All this works completely automatically, theres nothing youll have to do; the GUI is just for being able to watch whats happening.
Main features:
- Input file checking: as soon as an image is put into the archive, ImageServer checks the extension to see whether it really is an image. If not, it is put into a specified folder outside of the archive.
- If configured to do so, an image without a suiting name is assigned a new name which is constructed of both the subfolders it resides in and a unique-per-subfolder serial number of arbitrary length.
- When detecting a change in the masterArchive, ImageServer can play a sound.
- When starting to convert an image, ImageServer can play a sound.
- ImageServer can remember the names it has already assigned to images in the past. This way, names assigned to an image A will never be assigned to another image B after A has been deleted.
- Any number of slaveArchives can be defined, and they can be in any location.
- Each defined slaveArchive can have completely different settings for the images that will populate it. Resizing or resampling? RGB or CMYK? Jpeg, EPS, PNG or TIFF?
- You can choose whether each slaveArchive should inherit the exact same directory structure from the masterArchive or whether the slaveArchives images should all be put into the same folder.
- In case dazuko missed something, you can tell imageserver to manually look into a folder. It can then either process all images in that folder or only those where slaveArchive-images are missing.

Kat is an application for KDE designed to index files. Meta information, fulltext and thumbnails are extracted from documents, images, mp3 and other media allowing quick and accurate information retrieval.
Similar to the Windows application WhereIsIt, but also similar to Google Desktop Search, Kat is completely written in C++, using Qt3, KDE and KIO libraries.
The application is based on the extensible kfile plugin architecture of KDE in order to facilitate the creation of new media managers for emerging file formats.
Kat is the first KDE application using the new fulltext kfile plugins.
Information retrieval relies on the powerful SQLite3 embedded database engine.

Multi_Search is a desktop search widget for Superkaramba.

Requirements:

NOTE: A new requirement for version 0.1.0 is the wxPython module. You will not be able to use the new options in this version without wxPython. If you choose not to install wxPython you can still do the old configure options such as change background/default browser/and add search engines, but none of the new features, those need wxPython.

What It Does:

This widget allows one to search almost any search engine right from their desktop. It also gives the ability to run terminal commands. The theme launches the search in your default browser(setup in the right click Configure Theme menu). Click on the icon to the left of the searchbox to change the search engine.

You can add your own search engines to the widget through the right click Configure Theme Menu. This will take a search url and add it and its associated favicon, if it has one, to your widget.

You also have the ability edit and remove existing search engines and change the icon for a search engine.

There are also 8 backgrounds to choose from which can be found in the right click Configure Theme menu.

If anyone has any problems, comments, or ideas I would be glad to hear them.
