Double redirect?

Question

Search Engine Optimization

I set a redirect in htaccess
RedirectMatch 301 ([0-9][0-9][0-9][0-9][0-9]) selftrips.ru/?p=$1
which translates, say,
selftrips.ru/2015 /07/27/21219
to
selftrips.ru/?p=21219
Further, according to the settings of permalinks, the waterpress transfers to
selftrips.ru/strany-i-mesta/aziya/turciya/sivas-ka...
after checking the server response via https ://webmaster.yandex.ru/tools/server-response/
Yandex sees 301 redirects and page selftrips.ru/?p=21219
1. Why does it see an “intermediate redirect”?
2. Do I need to fix this (so that end pages, and not intermediate ones, get into the indexing)?
3. If it is necessary to correct, then how?

Answer 1

RewriteRule ^[0-9]{4}/[0-9][0-9]/[0-9][0-9]/([0-9]{1,})$ http://site.ru\?p=$1 [L,R=301]

one or more times [0-9]{1,}
The first parenthesis is $1(......)
