Yes, yes, yes, and yes.

Yes, we can say that real search is possible with SignWriting documents.
In 2004, there was a paper presented at Lisbon by Antonio Carlos da
Rocha Costa, Gracaliz Pereira Dimuro, and Juliano Baldez de Freitas.
The paper was titled "A SIGN MATCHING TECHNIQUE TO SUPPORT SEARCHES IN
SIGN LANGUAGE TEXTS".
Although, not an implementation of their design, the advanced search now
available in SignPuddle addresses the same issues.
Guylhem Aznar discussed this same issue. He called the slight symbol
positioning differences between signs "Intra-personal variation". He
correctly states that:
/Such near-imperceptible variations in the fine positioning are due
to the human manual positioning of the symbols. It is nearly
impossible for two SW signs, even while using the same set of
symbols, to share the exact position for every symbol on the sign
canvas : the relative position of the symbols to the center of the
He suggested that these variations should be prevented. I've gone the
opposite way and embraced the existence of slight variations. The signs
in SignPuddle Online demonstrate the variability of the SignWriting
script. The advanced searching of SignPuddle show that these variations
are not a problem.

Yes, please do. I am very proud of the new search, both in terms of
flexibility and speed.

So far, symbol frequency does not include sign texts. The option will
be available soon.
