Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

 Appl.No 19055475 Applicant WORK TOGETHER MARKETING CONSULTANT LIMITED Inventor ChiKui MAK

A preparation method of a bismuth ion filter membrane includes: placing a filter membrane substrate into a cleaning machine, adding a non-ionic chelating agent solution and water, treating the filter membrane substrate for 1-2 hours, then dehydrating the filter membrane substrate to obtain a filter membrane substrate A; adding the filter membrane substrate A and a chelated bismuth ion solution to a reactor, followed by adding a chelating agent solution, and reacting to obtain a filter membrane substrate embedded with bismuth ions; and dehydrating and drying the filter membrane substrate embedded with the bismuth ions to obtain the filter membrane. Due to the bismuth ions, it can develop bactericidal effects within a distance of 1-3 feet and also enhance negative oxygen ions. Using the bismuth ions to make filter membranes and masks provides a cost-effective material, which is ten times cheaper than silver ions, making it economically advantageous.
