Federated search refers to a technology by which a collection of data sources belonging to a number of search engines or databases are presented together for ease of access. It allows searching in more than one search engine or database all at a go. But then again, what are some of the examples of federated search, and how can we make good use of this tool without difficulties across the spheres of life? Read on and you have a clear idea of what federated search is, how it works, and the real-life applications of the concept.
What is Federated Search?
The very idea of federated search comes from the necessity to cope with the blooming amount of information, meaning that every year, as many databases are being created around the world, the sought data can quite represent a problem.
Federated search comes to the rescue, it basically sends queries to databases as a group; after having been put to the relevant databases, they are compiled. The accumulated data is then ranked and then put to the user. That’s one way of avoiding the necessity to retrieve independently from each database, hence making the search for the user much easier and more expeditious.
Let’s visualize the concept with some concrete examples of a federated search. These examples will further clarify the mechanism and the practicality of the tool.
How Federated Search Goes in Academic Research?
Academic research is a key area of application for federated search. It involves the search from different databases in order to get the most relevant and current papers, articles, and journals. A federated search would then humanly do such roles but more efficiently—consolidating numerous databases into a single central system for search. Such a system would save researchers much toil and time since the system would present them with only the most relevant results.
A federated search system may combine ProQuest, JSTOR, Google Scholar, and others. The researcher does the search in one platform; this ranges from accessing all these independently and incurring a cost for each search done. Thereby making conducting a literature review, data collection, or data analysis very easy. In other words, the process is streamlined, and search results are comprehensive as never seen in any of the traditional means of undertaking a literature review, for example.
What’s the Role of Federated Search in Online Retail?
An example where federated search is applicable in practice is online retail. The use of federated search is useful for an e-commerce store with the likes of Amazon, which comprises millions of products from all sorts of categories. An online query in a product goes through various categories and databases.
In this case, a federated search offers the user simultaneous access to various product databases. The search engine scours through product descriptions, customer reviews, and seller information to bring up compiled results of what it deems most relevant.
This way, it improves the experience, and the chances of the customer finding just what he is looking for increase. It will save him a lot of time and trouble, and it will return more traffic to the online store for a retailer. Be it searching for a book, home appliance, or a piece of clothing, federated search opens up an avenue to peruse a well-compiled, complete list of search results.
Advantages and Limitations of Federated Search
However, like any other technology, federated search has its own set of advantages and limitations. Some of the biggest pros include real-time access to the latest data. This is mainly because fetching in federated search happens directly from the source databases in the federated search mechanism.
Another pro is the fact that it helps to prevent the information overload of data. When the data is compiled, duplicated, and even ranked, then it is much easier for the user to end up with the most satisfactory results without necessarily bushwhacking from one irrelevant or repeated piece of information to another.
On the other hand, the federated search system could be prone to a slower response time: the speed of retrieval entirely depends on the response of all queried databases. If one hesitates or does not reply, then it may lead to the slowing down of the whole search process.
Another possible limitation is the accuracy of the results. In native ranking algorithms, relevance is judged by the search and depends only upon the database. This means that relevant hits can be downgraded with those algorithms not perfectly tuned. Altogether, federated search is just the thing needed for information whereabouts in the digital age. It very obviously holds a place in academic research and even in online retail, but the scope of its application is skyrocketing with more advanced technologies.
