Search capabilities on a content-based blockchain like Hive is a basic functionality as there is much value encapsulated in it and users need to be able to find fast and pretty exact what they are looking for. And on top of that using the search capabilities someone could find if somebody else posted on a specific subject to avoid duplicates or posts that addressed one problem or the other. Or simply use it for research to identify whatever you need or remember a reference to something useful that you once read. So let's see what search options we have on Hive blockchain.
Hivesearcher is the prime dedicated search engine on the Hive blockchain. With a clean user interface, you can search fast using specific keywords. Once results are retrieved you can sort them by Relevance, Popularity or Most Recent. A must-to-use tool with basic search features on the Hive blockchain.
Ecency is an entire frontend for Hive blockchain which also has a Search functionality embedded within. Actually, I believe it uses the Hivesearcher engine and simply embeds it within the site. On top of that, I like this frontend as you are awarded Points for being active using it and you can use those to boost up posts with HIVE upvotes.
Google as the most used search engine in the world indexes all the content created on the Hive blockchain. Thus it makes it also a good tool to search for specific keywords and use specific terms to localize the search. You can simply search something like "PolyCUB" and add keyword as "site:leofinance.io" and you can find posts on a specific Hive frontend. Replace the site with something else to expand the results.
Search still represents a challenge to retrieve fast and using additional filters on Hive blockchain. Leo Finance expressed the intention to implement a search engine fulfilling this demand and we quite need some refinements on that. Still, we have quite few options until new solutions will come to market.
