Well, I was referring to the seeker of each blog. At least, the seeker of my blog.
For example:
Search: "cristales" ("crystals" in English), and appear news that are irrelevant.
http://elboligrafo.es/?s=cristales
Some news irrelevant:
1. "Scientists discover the origin of vertigo" ("Científicos descubren el origen del vértigo" in Spanish)
2. "Eighteenth-century Swedish ship in Kiel Bay" ("Nave sueca de siglo XVIII en bahía de Kiel" in Spanish)
3. "The moons of Jupiter and Saturn meet the conditions for life" ("Las lunas de Júpiter y Saturno reúnen las condiciones para la vida" in Spanish)
Greetings and thank you for your attention,
