@MartinR please share an example link here, i don't see issue with simple one like this: approach0.xyz/search/?q=OR%20content%3Ahello&p=1

@WeiZhong Is there any way to exclude AoPS matches (they are unwanted noise when searching for dupes for math.SE; they slow down my dupe search process by a significant factor).

@WeiZhong That's unfortunate. It means that Approach0 is no longer useful to me any more. If this is ever fixed could you please let me know. Thanks.
@BillDubuque You asked to be notified when A0 has possibility to restrict the result to some domain. There were also some other changes, which are listed here: chat.stackexchange.com/transcript/46148/2021/6/7
I will admit that I do not have some very straightforward way to enter a query restricted to one site, but I suppose the software will evolve in the future. (And also I will get more acquainted with the freatures over time.)
Here is an example - searching for $(a^2+b^2+c^2)(b^2+c^2+d^2)=(ab+bc+cd)^2$ without any restriction.
And here is a search only on MSE and only on AoPS.
I will add that typically when I'm searching I do not mind seeing results from various sites. But it is probably good to know that I can switch to a specific site. (And if several other sites are added, I might actually start using this more - at the moment, there are only two.)

@MartinSleziak Thanks a million Martin. That is great news. The problem I often have is that the MSE search results list isn't lomg enough enough because too many entries are allotted to AoPS matches. Now restricting it to MSE I may find more and better MSE matches since the list of MSE matches may now be 2-3x longer in those cases. Further, I don't have to waste time visually filtering AoPS matches (which have no relevance for dupe targets).
I presumed it was a trivial enhancement - not something 1.5 years in the making. But better late than never.
 
@WeiZhong I cannot reproduce the problem anymore, everything is working as expected.

@WeiZhong Thanks much for implementing the ability to restrict searches to Math.SE. This will make Approach0 much more useful for those of us who seek to better organize Math.SE (which is absolutely essential for its continued success).

How does one use the UI to enter the Boolean queries using SITE and TAGS? It is not obvious nor is mentioned in the user guide.

@BillDubuque Sorry I did not recall your previous message and forget to inform you about this. Basically approach0 is implemented almost from scratch, so it takes time to involve. Due to some speicial things in Math search, it is tricy to actually implement this fitler, although it does look simple even to me at first... and it about implement it in an efficient way.
@BillDubuque i am glad you feel it becomes useful again.
i have not written any official documentation about how to use the filter yet, currently i am in a travel mode (leaving China in a few days) and there is a paper due in
a few days. I will probably update user guide later, for now, you may refer to previous examples in this room for more information on the new query format.
@BillDubuque refer to these examples for now: https://chat.stackexchange.com/transcript/message/58259823#58259823
For UI, a canonicalized form of input would be: Enter boolean filter such as AND, OR or NOT in capitals, following a space, then enter FIELD:keyword where keyword should be wrapped with dollar if it is a math keyword, and FIELD is a field name, now it can be: tags, site or title.
@MartinR thanks for the update!

@WeiZhong: A thin space \, is sometimes used in integrals, between the integrand and the integration variable, e.g. $\int \sin(x) \, dx$. However, the new UI transforms that to OR content:$\int \sin(x) \, OR content:dx$ .
 
8:03 AM
Since now the new changes are also on the "official" version, I will copy-paste the examples from here chat.stackexchange.com/transcript/46148/2021/6/7 - with the updated link.

@MartinSleziak thanks.
@MartinR that is definitely unexpected, i am going to fix that.
thanks for reporting it!
