Cette checklist date un peu mais elle contient de bonne idées :
* Accept multiword keyword searches, without requiring SQL commands or Boolean operators.
* Find matches on some or all words as keywords, as well as phrases
o Better to find something than nothing.
* Allow customers to enter product codes and product brand names as well as general topics.
o Make repeat customers happy
* Default to searching all the product information, but recognize a few special fields, such as size, color and price (see faceted metadata search)
* Include synonyms, so a search for “red sweater” will find scarlet cardigans and magenta crew-necks.
* Include site information, such as order status and return processing.
* Index extensive product information, even if it’s stored in back-end databases
o Few database search engines are both easy to use and flexible, see the SearchTools Report on Database vs. Full-Text Search.
* Sort results so the most likely to be relevant items come first.
o Perform user testing to learn what relevance means to customers
o Analyze your search logs to find out what people ask for and where they go
o Adjust the search indexing to include everything that’s useful
* Format results listings to show the most valuable information:
o Emphasize the matching text using bold or colors, so it’s clear why the item was found.
o For physical products, such as clothes or groceries, show pictures.
o Show the most important elements, such as price, size, brand name or compatibility information.
o Include inventory status, so it’s clear what’s available and what must be backordered.
* For searches which don’t find any matches, provide a clear and helpful error page.
o See the SearchTools Report on Search Failure and the report on No-Matches Pages
* Generate a search log, which store operators can consult for free market research:
o what’s popular
o what’s trending down
o what customers look for that you don’t carry
o what misspellings and typos they commonly make.
