url và email trong kết quả tìm kiếm solr

Question

Tôi có tìm kiếm solr trả về kết quả nổi bật theo ngữ cảnh hiển thị url và email có khoảng trắng sau dấu chấm - như "www. Google. Com" hoặc "email @ google. Com" tắt tính năng này, vì vậy chúng hiển thị bình thường? Cảm ơn.

Query:

/solr/core1/select?q=email&start=0&rows=10&sort=score+desc&fq=%28categories%3A%28*8*%29%29&wt=javabin&version=2

Answer 1

Hãy thử sử dụng UAX29URLEmailTokenizerFactory tokenizer, giống như trình mã thông báo chuẩn nhưng có thể nhận ra địa chỉ email, URL, tên miền và địa chỉ IPv4/IPv6. Một ví dụ từ Reference Guide Solr:
