The role of your mind in searching
Of course you are involved with every search you perform, but I’m not convinced many people understand how symbiotic the relationship is between themselves and the search engine.
I believe that aggressive searching includes a mindset much like playing a sport. Beginners stand there and wait for things to happen, but real players understand the dynamic of their own actions. To be a good player, you must be working to make things happen in your favor.
In searching, this takes the form of devising good search terms and synonyms, remembering what you have used before, quickly abandoning unproductive results, using search engine operators and in general being creative in your search.
Beginning searchers go to a search engine, type in a word or two and pray.
