Does capital or small letters affect SERP result?

[jesicawillss]

I saw this kind of problem first time. My keyword “software development India” is showing different SERP results. If I search for “software development india” then it appears at 153 in Google for perceptionsystem.com and if I search for “software development India” then it appears at 20. It means, it is showing different results for SERP.
Does capital or small letters affect SERP result? Is there anyone expert to answer this?

I get some stunning positive placements when using asterisk before the word I search on.
Heard it mentioned in here and tried it out, still don't know why it would do this.

I am agree with web.hostingmadnes.You will get same result with capital letter or with small letter.

First of all, both the search terms that you have used are of same case. Search engines as of now, are not case sensitive. So, there is not going to be any difference in the SERP results for any case.
