A very good enterprise search application. Search results are produced pretty fast and the contents gets re-index quite often which ensures that the search results are not stale. The Administrative Interface is very easy to use and has a lot of useful information. The number of pages crawled by google search appliance is quite high compared other tools in the same domain. Another good feature of Google search appliance is that, the search index keeps getting updated for every update to any doc and removal of any doc actual clears the corresponding entry in the search index ensuring that non-existent entries don't show up in the results page. Search results can be grouped in various collections e.g. university collections, medical collections etc. Google Search Appliance very smartly handles the synonyms, as can be seen in the "narrow your search" feature. Indexing of content can be easily configured by specifying URLs
Room for Improvement:
Google Search Appliance sometimes takes more than the usual time to crawl and index data. Also due to this, the search results sometimes keeps showing older and non-existent data. The way, search algorithms work is totally hidden and there is no option to tweak any of the internal algorithms to change the search results. The ordering of search result is quite random and it is often seen that the most relevant search result is not shown in the top, which is quite confusing.
A very good enterprise search application with a good administrative user interface which is intuitive and easy to use. The re-indexing rate is quite high and this keeps the search results updated. It can crawl a large number of web pages in a very short span of time. It smartly handles synonyms. However there are some issues with the search results produced. It is seen that the search results produced are ordered as per relevance and they seem to follow some random order. Indexing of content can be easily configured by specifying URLs.
