The search operation on both questions and posts doesn't work. I get the same set of results for both, and the same results regardless of the search term.

When I login and then create a question or post and click submit (or preview), I get a new request to login, and, after I do that login, the originally entered message body has been erased.


My Homies

I'm trying to find words which contradict the rule "i before e except after c". according to BBC program "QI" there are 923 exceptions, but below i get less than that. i guess its only as good as the dictionary, the 'inbuilt' has only 25k words but 'ospd3' (with 80k words) seems to stop before letter Q (with my sledgehammer code) when there are more words out there like "weird", "veil" and "reciept".

with(StringTools); with(PatternDictionary); bid := Create(ospd3);
words :=([seq])(LowerCase(Get(bid, i)), i = 1 .. Size(bid)-1);
tot := 0;
for n to nops(words) do
C := searchtext(cie, words[n]); E := searchtext(ei, words[n]);
if`and`(C = 0, E = 0) then next else tot := tot+1;
print([tot, words[n]]) end if
end do



I have a list of sets eg. L:=[{a},{b,c},{d,a,f},{b,d}] and I'm having problems doing operations on it. 

I want to be able to take the first element (a here), look for the next occurrence of it and return what is in the set with it (here d and f).

However I can't seem to use Search or Occurrences as they consider the sets themselves to be the elements. For instance Search(a, L) returns 0. 


What can I do?

I'm using Linearalgebra where I have a 10x1 matrix. I want to find the closest element of the matrix to origo, and the furthest away from origo. Can anyone help me to a understandable solution? :)


Is there a way of searching a list for two consecutive numbers?

Eg. I have the sequence:


I would like to ask, what is the way to use the Direct Search (or other similar package) to solve not a static optimization problem for, say f(x_1,x_2), but the dynamic one, say for f(x_1(t),x_2(t),t)?

I think there must be the way of adapting the algorithm for that.

Any ideas welcome.


Cannot find own answer in

via searching in my answers. Is it because original message is too old and thats why should be so?


How could we know which command to use to do a specific task such as:  "convert boolean value to {1,0}" . I know we could use evalhf() but if we search with keyword "convert true false to 0 1 " in the Maple help then we may not find the right command

Using the Online Help is a solution but I want to know an offline solution since I am not always with the Internet. Did anyone wrote a summary sheet with the content such as : (i.e a list of all commands with keywords for searching)

Hello to all,


I have a chunk of letters, numbers and others symbols like in this extract:


My goal is to be able to enter that chunk into Maple for character manipulation like searching if, for example, Qxp+zr6km is part of that chunk as is (and if possible his location).  Since there is some "+", I can't define it with chunk :=.  The source is a *.txt file.  Maybe a readdata?

I am quite busy for the moment so is there someone kind enough to help me.

Thanks in advance

Is it possible to search a variable or any word or a command in a long worksheet

Thanks in advance

Hi Experts,

Here is my File. I use the DirectSearch2 Library.

Searching the Minimum works fine. (800 sec on i7 PC)

But the Datafit runs endless.

I tried to make the fit with min SSE that works, but why does DataFit not succeed?


Thanks for answering.


I want to search maple files for specific texts within the file.  What software will do this?

I recall some mention before about searching for specific texts in maple documents but I cannot find it. 

If I search for something in mapleprimes then click on one of the selections, mapleprimes brings me to a page of many posts and does not bring me to the proper single post I expect to see.  In fact the post or question I selected does not even exist in the next page mapleprimes sends me to.

I don't seem to be able to get Help to respond to searches with more than one keyword...for example, I entered "date format" and received "No Matches Found."

Search misses...

I notice that a Seach on this site for the word "cipher" fails to show this result as a hit. Why is that?

It is by no means the first time that a keyword Search on Mapleprimes has failed to return a hit for an old comment/post/answer of mine. I'd really like to know why there are so many such misses.
