How to implement Autosuggestion
Hi All,
I've a query regarding autosuggestion. My use case is as below:
1. User enters product name (say Nokia)
2. I want suggestions along with the category with which the product
belongs. (e.g Nokia belongs to "electronics" and "mobile" category) so I
want suggestion like Nokia in electronics and Nokia in mobile.
I am able to get the suggestions using the OOTB AnalyzingInFixSuggester but
not sure how I can get the category along with the suggestion(can this
category be considered as facet of the suggestion??)
Any help/pointer is highly appreciated.
Thanks,
Chandan

Hi Alessandro,
Thanks for replying!
Here are my answers inline.
1. "First of all, simple string autosuggestion or document autosuggestion ?
(
with more additional field to show then the label)
---- Document autosuggestions
2. Are you interested in the analysis for the text to suggest ? Fuzzy
suggestions ? exact "beginning of the phrase" suggestions ? infix
suggestions ?"
--- I am interested in analysis for the text to suggest.
3. In the case you want to show the label AND the category AND whatever ( in
Amazon style to make it simple) .
A very straighforward solution is to model a specific Solr Field for your
product collection.
This field will contain the name of the product, analyzed according your
need.
Then your autosuggester will simply hit that field on each char typed, and
you can show the entire document in the suggestions ( with all the fields
you want) .
---- Not sure what you mean by indexing a field with the name of product
analyzed according to my need? Can you please give an example?
Thanks again for taking time to respond to my query.

Hi Chandan,
I will answer as my previous answer to a similar topic that got lost :
"First of all, simple string autosuggestion or document autosuggestion ? (
with more additional field to show then the label)
Are you interested in the analysis for the text to suggest ? Fuzzy
suggestions ? exact "beginning of the phrase" suggestions ? infix
suggestions ?"
If you need only the category *payloadField* should be what you need .
I never used it as a feature but it is there [1] .
As Reth suggested, at the moment Solr supports only one payloadField,
ignoring the others ( code confirms this).
In the case you want to show the label AND the category AND whatever ( in
Amazon style to make it simple) .
A very straighforward solution is to model a specific Solr Field for your
product collection.
This field will contain the name of the product, analyzed according your
need.
Then your autosuggester will simply hit that field on each char typed, and
you can show the entire document in the suggestions ( with all the fields
you want) .
Or we take a look to the implementation and we contribute the support for
multiple *payloadField*.

There is a payload attribute but I'm not sure if this can be used for such
use case. Lets wait for others contributors to confirm.
Similar question posted here:

.
If its just a category that you need then the work around(although not
accurate one) that I can think of is to include the category value to the
same field with pipe separation and extract from it?
