How to rewrite url for url with multiple query parameter?

Question

Server: Nginx

Application: PHP

URL in question is

/p/all_articles/user/ABC

/p/all_articles/user/ABC/page/123

which is

/index.php?p=all_articles&user=ABC

/index.php?p=all_articles&user=ABC&page=123

ABC = this could be a-zA-Z0-9 as it's username
123 = this could be page numbers 0-9

Tried many combinations and options, the following got me much closer to expected result, but it is not perfect.

location /p/all_articles {
    rewrite ^/p/all_articles/user/(.*)?$ /index.php?p=all_articles&user=$1 last;
    rewrite ^/p/all_articles/user/(.*)/page(?:/([0-9]+))?$ /index.php?p=all_articles&user=$1&page=$2 last;
    try_files $uri $uri/ /index.php;
}

the above rewrite location block results only when one of them is quoted other one would work, but not together.

Similarly

/search/QUERY

/search/QUERY/page/123

which is

/index.php?search=QUERY

/index.php?search=QUERY&page=123

QUERY = anything a-zA-Z0-9 and space
123 = this could be page numbers 0-9

like the one for all_articles, the closest I was able to get is

location /search {
    rewrite ^/search /index.php?search last;
    rewrite ^/search/(.*)/page(?:/([0-9]+))?$ /index.php?search=$1&page=$2 last;
    try_files $uri $uri/ /index.php;
}

But, this works to get either one of the clean URL when the other rewrite is quoted, but not together.

I appreciate if anyone give any answers to solve this issue.

The rewrite statements are evaluated in order so the more specific regular expression needs to be placed before a less specific regular expression.

With the two regular expressions:

^/search
^/search/(.*)/page(?:/([0-9]+))?$

The first one will match anything that also matches the second, so the second regular expression will never be evaluated.

The simple solution is to reverse the order of the rewrite statements in both of your location blocks.
