Dear Guru Maharaja,

Please accept my humble obeisances.
All glories to Srila Prabhupada.

It took long time, but search on Vedabase.io is pretty useful now. 

There is help text on search page which explains different features (boolean, proximity, ......)

English: https://vedabase.io/en/search/

In English is possible to narrow down results by type - book, transcript, letter. In other languages there are only books so far so this filter is not available.

Spanish: https://vedabase.io/es/search/ (help text is still in English, but Spanish search page searches through Spanish texts)

More filters will come, but already now can give you good results when you search for something.

Spanish importing stopped. But recently Bhakta Marco from Mexico joined to help, finished missing 2 chapters in Adi lila (https://vedabase.io/es/library/cc/adi/) and is working now on Madhya Lila.

HpS - ASA -  This report, news, is worth a million dollars!    Thank you so much.  We use the search function many times. We can remember part of a verse or a quote from a purport and then find it. Thank you..  Do you need more people to help with the importing work in Spanish?????
