How to enable Did you mean feature in Adobe Search and Promote | Enable Guided Suggestions in Adobe Search and Promote

This tutorial explains the details on “Did You Mean” feature in Adobe Search and Promote.

You can configure “Did You Mean” so that customers are given suggestions for valid search terms when they have tried searches that have failed. Suggestions are formed by looking for spelling and typing corrections to the search terms that result in a valid search.

This feature helps to avoid the null search due to wrong spelling of words in the search term and improve the conversion.

Configuring Did You Mean

You can tailor how site search/merchandising makes search suggestions when a customer’s query returns no, or minimal, search results.

To enable Did You Mean feature, access Linguistics → Did You Mean

Remove these Words from Suggestions — enter space or line separated words to filter undesirable suggestions.

Suggestion Algorithm — Adjusts how far the software goes to find suggestions. If a user makes a one-letter mistake, all of the algorithms come up with the same suggestions. The reason why is because it only takes one edit to arrive at a working suggestion, and all algorithms find words that are close to the original. But when the original search terms are not similar to existing terms in the index, the Deep and Bad Spellers Suggestion Algorithms continue to search for possible suggestions. This scenario is useful if a customer tries a proper name that is hard to type, and they sound out the names. However, if you only want similar suggestions to appear, you can choose the Quick algorithm

Default count of suggestions to show — Specifies the number of Did You Mean term suggestions (0–20) that you want to show when a customer’s search returns no results. The default is 3.

Minimal suggestion word length — Prunes Did You Mean terms by specifying the minimal number of letters for a suggested word. For example, if you set the value to 4, the software does not suggest a word that is 1, 2, or 3 characters long. If you specify a value of 0, no short words are removed from the term suggestions. If you specify a high value, it usually results in no term suggestions. The default value is 3.

Minimum index frequency — Specifies the minimum number of times a word has to appear in the index before it is included in the Did You Mean dictionary. You cannot specify a negative number in the field.

Search for suggest term if no results — Automatically re-searches for the first suggested term when a customer’s search yields no results and there is at least one Did You Mean term suggestion.

Make suggestions due to low results — If a customer searches for a term that yields less than ten results, the search engine checks to see if it has a suggestion that can yield more than 100 results. The number of suggestions is controlled by the value that is specified in Default count of suggestions to show. The low and high threshold are configurable by the options below.

Make suggestions when the initial results are fewer than — Controls the number of results when the system starts to offer suggestions. This option appears only when you check Make suggestions due to low results. The default is 10.

The Did You Mean functionality can be enabled in three ways: make suggestions due to no results, automatically search against the first suggestion when we have no results, or make suggestions due to low results (where the suggestions have a higher result count).

Let us enable the indexing with IndexConnector(the URL entrypoint can be used if required), refer the below URL for details on enabling IndexConnector and configuring custom templates.

The sample feed data for indexing, enable the required metadata, IndexConnector, URL entrypoint and the custom templates by following the previous tutorial URL

Enable the transport template — custom_backend_json.tpl

Enable the transport template — custom_presentation_json.tmpl

The configurations are ready, let us now run a Stage indexing (note the configuration are not pushed to live yet)

Index →Full Index →Staged Index →Run Full Index

Let us now test with the default “Did You Mean” configurations

Access http://stage-xxxxxxxxxxx.guided.ss-omtrdc.net/do=json&sp_staged=1&q=bava

xxxxxxxxxxx — Search and Promote account number

There is no matching data for the term “bava”, this will provide all the available suggestions with search link and search value those data can be used to show the suggestion to the users.

{
"general": {
"query": "bava",
"total": "0",
"page_lower": "0",
"page_upper": "0",
"page_total": "1"
},
"suggestions": {
"auto_searched": "0",
"suggestion_low_result": "0",
"suggestion_items": [
{
"path": "?do=json;i=1;q=lava;sp_staged=1",
"value": "lava",
"count": "1"
},
{
"path": "?do=json;i=1;q=java;sp_staged=1",
"value": "java",
"count": "1"
}
]

},
"facets": [],
"results": []
}

Let us now enable “Search for suggest term if no results” option — Automatically re-searches for the first suggested term when a customer’s search yields no results and there is at least one Did You Mean term suggestion.

Image for post

Access http://stage-xxxxxxxxxxx.guided.ss-omtrdc.net/do=json&sp_staged=1&q=bava, this will provide all the available suggestions(other than the first suggestion used for auto search) and returns the result by searching with first suggested term.

{
"general": {
"query": "lava",
"total": "1",
"page_lower": "1",
"page_upper": "1",
"page_total": "1"
},
"suggestions": {
"auto_searched": "1",
"auto_search_query": "lava",
"original_query": "bava",
"suggestion_low_result": "0",
"suggestion_items": [
{
"path": "?do=json;i=1;q=java;sp_staged=1",
"value": "java",
"count": "1"
}
]

},
"facets": [],
"results": [
{
"index": "",
"title": "Lava Title",
"productType": "Lava"
}
]

}

“Make suggestions due to low results” — if a customer searches for a term that yields less than ten results, the search engine checks to see if it has a suggestion that can yield more than 100 results.

Image for post

This will return “suggestion_low_result”: “1” and the available suggestions that yield more than 100 results but somehow the scenario is not working as expected. I will be updating the tutorial with further details.

The configuration can be pushed live after successful validation and run a live index →Full Index →Live Index →Run Full Index

The URL to access live data http://xxxxxxxxxxx.guided.ss-omtrdc.net/do=json&q=bava

The suggest data returned can be used to enable the “Did You Mean” functionality in the website.
