We are constantly improving our Magento Advanced Search Extensions and every week an updated version for at least one extension is released with improved functionality.
Search Spell-Correction Magento Extension is updated fortnightly, new algorithms are added and current ones are improved. Each change in the search algorithm of the correct words has a definite goal: improving productivity, improving relevance, and search for new forms of corrections.
But after every change there is a risk that the words / phrases that previously were corrected properly, in the new version will not work.
To keep tracking the quality of new versions corrections, we use a simple but effective way to compare the results – test phrases.
We form a spreadsheet:
| Target phrase | Error phrase |
|---|---|
| samsung | simsung |
| samsung | samsing |
| samsung | asmsung |
| samsung | samsng |
| samsung | samung |
| samsung | sansung |
| samsung | samsg |
| camera case digital | cameracasedigital |
| camera case digital | camera casedigital |
| camera case digital | cameracase digital |
| camera case digital | camra case digial |
| camera case digital | camera caedigital |
| camera case digital | camer cise digutal |
| apple | applee |
| apple | aplle |
| … | … |
In general, the table consists of about 500 different combination which are entered incorrectly. Then our programmers simply run php script that displays a summary comparative spreadsheet:
| Target phrase | Error phrase | Found phrase | Similarity of the source phrase to the target phrase (%) | Similarity of the found phrase to the target phrase (%) | Time (ms) | Result | |
