I appreciate your work and am looking forward to using it; it seems that I am not alone in this, given that your post currently has 12 - 1 votes. There is one problem though: starting by the end of August, you have posted on MSE a number of answers that only advertise your search engine and point to duplicates found with the said engine (half of those ...
Searching for a specific formula is often rather difficult. A tool which is very suitable for this is the Approach0 search engine.
Some basic information can be found in Guide for New Users (which contains also animations of some examples). If you want to know more about the project, you can look at the documentation.
Approach0 uses mathquill ...
This does not address the question at all, but perhaps we could make a list of names which are frequently mis-spelled (or have variant spellings/Romanisations).
Please add more to this post, but try to keep the list in "alphabetical" order and include a link to a math.SE search for each variant. Perhaps put in bold the correct/preferred spelling, if any. ...
See my side-project, it is an open-source math-aware similarity search engine.
I am hoping someone interested can join and form a community to push this project forward, this is the reason I am posting here.
If you are interested at this project, please follow it on twitter: https://twitter.com/approach0. Approach0 will post updates ...
See my side-project, it is developing its indices currently.
I will publish its first release when the entire math StackExchange is indexed.
Also, I am hoping someone interested can join and form a community to push this project forward, this is the reason I am posting here, even if this project is not fully ready for public using.
It seemed to me as a good idea to make a CW answer where Math.SE users could add the problems they stumbled upon while using this search engine. (EDIT: And we can also use this chatroom for discussing Approach0-related issues and searching for questions in general.)
I was unable to enter things like $\Bbb N$ $\Bbb N$, $\mathbb R$ $\mathbb R$, $\mathcal S$ $\...
What if we created something like a "Wiktionary" for equations?
A peer-to-peer site with a huge database of equations, linked to each other, with some description, their names, their related equations.
Blind to change of variables and substitutions, blind to alternative forms and notation, indexed, commented, and with clear links to Wikipedia (and other ...
Yes, you did your part, so feel free to add it.
In fact, to make it easier for folks to find it in the future, you can add statements like
I tried googling for "keywords", but could not find it.
(i.e. add some keywords to your question for easier searching in the future).
There are lists (on the meta and the main, separately) which you can access if you have 10k points or more, through review and then clicking tools and choosing the appropriate tab. These lists, however, do not include everything, they are limited in both time range and length.
The lists go only as far as 30 days the most. On the main site, however, due ...
One thing which we should keep in mind is that duplicates might be useful. They improve the chance that another user will find the question, since with each duplicate another copy with somewhat different phrasing of the title is added. So if you spent reasonable time by searching and did not find your question, it is not such a bad thing if it is later ...
LaTeX titles, etc. certainly affect Google search results. For a very obvious example, search for "$\sec^3 x \, dx$" site:math.stackexchange.com.
This demonstrates that Google looks at the raw LaTeX code, not the rendered result. (This is somewhat obvious after thinking about it, but it can be somewhat easy to overlook.) This means that you can search ...
searchOnMath looks interesting too. I think you can do what you want
Feb. 2019 Update from one the developers Flavio Gonzaga:
Recently our tool has indexed both: Mathematics and MathOverflow.
Currently, SearchOnMath is the mathematical search engine with the largest number of indexed sites (including Wikipedia, Wolfram MathWorld, among others ...).
Users with 10K reputation can access the Protected Questions list.
You can find this by going through the "review" link in the top bar, then choose the "Tools" tab and then the "stats" subtab, and finally looking at the "Links" towards the bottom of the page.
The SEDE can also be employed to find protected questions via the PostHistory table. Here's a ...
You can limit search to your own questions by adding the user: toggle. To search for one's own posts we can use user:me. For posts of other users use user:##### where the ##### is replaced by the user number of the user (you can find it out by hovering your mouse over the user's name card, the number is the first number that appears in the URL. For example, ...
Lists of questions
There are also various lists of questions which might help when searching for some topic (some of them generated by the Stack Exchange software, some of them created manually).
If you click on ask question and fill at least the title (perhaps also tags) the software generates a list of questions that are similar. As pointed out by some ...
You can use the normal search with the specification "infavorites:mine". When you are viewing search results, look at the "Advanced Search Tips" to the right of the search input field.
To search in someone else's favorites, use "infavorites:13854" where 13854 is replaced with the person's MSE id.
search your comments by keyword (the keyword can be the other user's display name, or something that was mentioned in the discussion)
get the list of your comments under posts by a specific user
browse all your comments
There's nothing in the site search capabilities that would allow this, although the Stack Exchange Data Explorer (SEDE) would allow you to create a query to achieve this goal. The only caveat here is that the data in the SEDE is only updated once every week (Sundays at about 03:00 UTC), and so what the query retrieves may not accurately represent the current ...
Besides browsing specific tags, you can also go to the Unanswered list. You can also filter that list and show only questions that have at least one of a list of tags, for example:
You can simply use Google with the restriction to this domain, using (in addition to the search query) site:math.stackexchange.com. (Of course, you can also use any other search engine where this restriction is possible.) For example, you can use the search: triangular numbers site:math.stackexchange.com to get to relevant posts about triangular ...
For example, I want to see all questions posted in sequences-and-series in September month of 2016.
You can used built-in-search for this. The modifier created:2016-09-01..2016-10-01 returns only posts from September. (I have added one more day to be on the safe side - and also to make this easier to modify.) If you are interested just in one month, you ...
You can use the Stack Exchange Data Explorer for these kind of things.
For Q1, this query lists the questions answered by the two highest reputation users on the site, but you can easily adjust the user IDs.
Q2 requires a slightly different query (I took your user ID and a random person who answered one of your latest questions).
Please note that SEDE is ...
If browsing through the comments list in your profile takes too long, you can search them through Data Explorer:
Search your comments (or another user's comments, by entering their User Id)
Comments left by a user on your posts (more generally, comments left by user A on posts by user B)
Search all comments
and my favorite
Posts edited after your ...
