[PNI] Search - update search fields/ranking

[Pomax]

Felds included in filter-search:

Currently:

• Product name
• Company name
• Blurb
• Worst case

Sorting/ranking priority of the results:

• Product name
• Company name
• Blurb

Potential third party libraries if we want ranking and a standard array.sort((a,b) => { ... }) doesn't cut it:
