crawling Google /other engines for research purposes

[soroka]

Hello,

for my research purposes I need a big amount of text data (gathered by
querying!)

Is there any legal way to get data by querying Google automatically
and storing the found pages?

The Google SOAP Search API is not supported any more and I could not
find any alternative API.

Are there any other possibilities to gather data collections by
querying from the web?

I think, there should be other researchers having the same problem as
well. How do you solve this problem then?

br,
Anna
