I will build a (Single Nucleotide Polymorphism) SNP database system, and there is a feature in the system to search. is there any method or technique that is recommended for search engines such as DNA or SNP.
Anyone know what method to use the NCBI site on search engines? I see there could do a multi-query search using logic "AND" or "OR". but I don't know what techniques are used.
I want to build using the PHP programming language.
