Search by keyword
The % is a match score: your keyword is split into 2-character pieces, and the score is the share of those pieces found in an item (title, heading, text or table row); if the keyword appears as is, it is 95–100%. For alphanumeric keywords, only matches from the start of a word count, so a misspelling may return nothing. It is not the probability that the answer is correct. Search runs only on this device, and what you type is not sent anywhere.

Number of spare batteries (lithium-ion) for cameras etc.
Sort them by the Wh printed on each battery (e.g. 7.3Wh goes in "100Wh or less").
