List of search criteria conditions in /main/src/pages/rest/use-rest/performing-searches.md is wrong

[aligent-lturner]

The list of conditions that can be used in search criteria is listed as:

Condition	Notes
eq	Equals
finset	A value within a set of values
from	The beginning of a range. Must be used with to.
gt	Greater than
gteq	Greater than or equal
in	In. The value can contain a comma-separated list of values.
like	Like. The value can contain the SQL wildcard characters when like is specified.
lt	Less than
lteq	Less than or equal
moreq	More or equal
neq	Not equal
nfinset	A value that is not within a set of values.
nin	Not in. The value can contain a comma-separated list of values.
nlike	Not like
notnull	Not null
null	Null
to	The end of a range. Must be used with from.

However, there are two separate issues with this, when looking at the actual code that executes:

1. moreq is not supported. Looking at https://github.com/magento/magento2/blob/011a4d0a5ad75945b2573ad01cd5815b1e4f6c52/lib/internal/Magento/Framework/DB/Adapter/Pdo/Mysql.php#L3235-L3259, we can see that it is not in the condition map.
2. regexp, seq, and sneqare valid conditions, but not listed - we can see these in the same code block linked in point 1.

Note that there are a couple of other conditions that are in the map, but are essentially useless, which is why I haven't included them in the list.
