When you use a word to query for some results, it will be difficult for the search engine to determine the intention behind making the query. If the word is so small or short to query, the work of the search engine will be even harder. To avoid this, they will use categories. The category label will be attached to the query word and this will make the understanding of the user’s intension easier for the search engine.
 
The search engines will use the results with the same phrase in their pages. Once these results are obtained, they will return those to the users and will rank them. The ranked results will be displayed to the users. Another option in which the search engines will handle the query is by placing this into a category and will look into all hierarchical categories to get relationships between the related terms. 

The higher level of hierarchy will be easier since this will be general and followed by the hierarchy at lower levels. This lower level will have categories that are more specific to the terms used in searching. In this way, when the term is placed into categories, the search engines will be able to determine what all items are connected to the term which you have used for querying which will make the results more relevant.

The usual way of fetching the web pages for you suggest a unique way of searching the database for the keywords users have entered.  Searching by categories bring a lot of difference as it fetches the necessary the pages in the context of the query. 

When a query is passed by the user, search engine assigns a special category to the query. Since the context in which the query has passed by the user is extremely difficult to figure out, search engine optimization techniques are refined to get the best possible search result.

By associating a category to the user typed query, it becomes much easier to identify the context. Search engine maintains a hierarchy of categories to associate user typed query. This preliminary hierarchy of category is pretty general in nature and this category is sub divided into many other categories that directs to the best possible exact context of the user desired search result. Say for example, preliminary category can include sports, entertainment, science etc, and hierarchy of sub categories can accommodate more specific areas like music, football, chemistry etc.

Hence the more refined technique which discussed very recently by experts greatly helps the searchers, writers or publishers to fetch more exact data and prepare categorized articles etc.
