Fast and efficient enterprise search application with query support in 40 different languages

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

Stable, scalable, and has testing and conversational AI features

The total time it takes to deploy IBM Watson Discovery depends on the documents you'll be working with. For example, I was in a situation where I was working with some painting files and folders for a painting store. The store had PDF documents, but the information was mixed up, so I had to treat the documents on IBM Watson Discovery, and discovering and understanding each PDF file took longer. The process is more straightforward for plain documents, and you have to work with questions that will help IBM Watson Discovery understand the documents. The time to deploy the product depends on the quantity and type of documents you'll be working with.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Good for enterprise search."

"A very good enterprise search application with a good administrative user interface which is intuitive and easy to use."

"Language support and the ability to build a natural language of speech recognition are the most valuable features."

"Being able to have some rules to extract the entities is valuable."

"The most valuable features of IBM Watson Discovery are the integration with the rest of the Watson Suite and the Watson Assistant capability. If you use Watson Assistant, the ability for it to be able to determine the accuracy of your voice models and your voice response systems is a benefit."

"Being able to have some rules to extract the entities is valuable. The capability to crawl external sites and internal documents, and then draw internal information with external contents is also valuable."

"It has allowed us to provide longer service availability for support to users."

"The most valuable feature of IBM Watson Discovery is testing, mainly because the product applies conversational AI, which means I can ask questions to get the information I want from a specific test area."

Cons

"Can't customize algorithm. Little bit black box because you can't customize search algorithm."

"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."

"The pricing is an area for improvement in IBM Watson Discovery because the customer initially used the free version. Still, when he needed more questions and documents, he had to move to a different version, which was paid and cost $500 per month. That change in pricing made my company lose many customers."

"IBM Watson Discovery has moved to a newer version and it is very difficult to train the newer version."

"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this."

"The support from IBM Watson Discovery is good but could improve to make it great."

"It needs a lot of memory. Our index is very big. It is around 100 gigabytes. So, we need more than 100 gigabytes of memory to use Watson."

"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this. Having said that, Watson is way more flexible. While it may require a greater amount of effort, it is not substantially more than some of the other ones that are kind of prebuilt for a specific use case. It would be good to have more prebuilt and specific use cases and specific business models. It can have better phone integration, even though I think that it is actually becoming less of an issue. Most people are online nowadays."
