What are the rules - you say that a query string of '10FTK' should match
'10FTH86RSK', but also '10FTK', '10F6TK', '10FTK4'
I think the problem is that the rules aren't 100% clear.
* For '10FTK' to match '10FTH....' you actually only care about the
first 4 characters ?
* For '10FTK' to match '10FTK...' implies you care about the first 5
* For '10FTK' to match '10F6TK...' implies you care about your 5
characters with an option numeric inserted after char 3 ?
so - should it match '106FTK ...' or '10TFK' or '10F99TK'
I can suggest a few strategies :
* With English spelling it is not common for a knowledgable to get the
first letter wrong - so you could find that the user will know they
want '10...' and that the 'FTK' bit might be mis-remembered - so
search on the first two characters only.
* Use the entered code to build a more fuzzy search - so 10FTK becomes
something like r'10*F.*T.*(K|H)' (for instance starting with the
characters '10' and looking for FTK or FTH with possible intervening
options.
* Typically long code words are difficult to remember - - is it
possible that '10FTH86RSK' actually represents a concept that can be
categorized and described in English - for instance rather than try
to implement a fuzzy search for the code, you actually provide a
user friendly categorization drill down; so the user works down a
tree of specific natural language descriptions - which internally
builds the code '10FTH86RSK'

Hello everyone!
Currently I am working on Django.
I defined a 'Search' function in views.py:
def search(request):
q = request.GET.get("q")
if q:
ReactResul = Reactionsmeta.objects.filter(id__contains=q)
MetaResul = Metabolites.objects.filter(id__contains=q)
GeneResul = Genes.objects.filter(id__contains=q)
else:
# you may want to return Customer.objects.none() instead
ReactResul= Reactionsmeta.objects.all()
GeneResul = Genes.objects.all()
MetaResul = Metabolites.objects.all()
context =dict(result_1=MetaResul, q=q, result_2=ReactResul, result_3 =
GeneResul)
return render(request, "Recon/search.html", context)
And now I want to make it more powerful.
If I want to search '10FTH86RSK' but I cannot remember the whole
name, I can just use part of the string to make query. For example,
if I type '10FTK', '10FTH86RSK' should be returned as result.
In that case, '10FTK', '10F6TK' or '10FTK4' should also be returned
as results.
So how could I achieve this function?
