// SearchService provides access to the search related functions
// in the GitHub API.
//
// Each method takes a query string defining the search keywords and any search qualifiers.
// For example, when searching issues, the query "gopher is:issue language:go" will search
// for issues containing the word "gopher" in Go repositories. The method call
//   opts :=  &github.SearchOptions{Sort: "created", Order: "asc"}
//   cl.Search.Issues(ctx, "gopher is:issue language:go", opts)
// will search for such issues, sorting by creation date in ascending order
// (i.e., oldest first).
//
// If query includes multiple conditions, it MUST NOT include "+" as the condition separator.
// You have to use " " as the separator instead.
// For example, querying with "language:c++" and "leveldb", then query should be
// "language:c++ leveldb" but not "language:c+++leveldb".
