1. Wildcard characters: an underscore ( _ ) matches any one character; a percent sign ( % ) matches zero or more characters.

2. All searches are case-insensitive. Also, searches are literal, not fuzzy; thus a search for reionization will not find reionisation, so this search benefits from using a wildcard, e.g., reioni_ation.

3. An ongoing effort aims to standardize name spellings throughout the data. However, there may be isolated cases where different series have slightly different spellings for a speaker's name, especially with or without diacritics. When entering search terms in the input boxes, you can use the wildcard characters _ (matches 1 char) or % (matches 0 or more chars) to help return all relevant data. For example, to get all talks data that include both Haïmoud and Haimoud, use ha_moud. Another example: for Renée Hložek, use ren_e hlo_ek or ren%hlo_ek. If you're not sure if a name in the database has diacritics, it's best to use wildcard characters when inputting search criteria.

4. Another example where wildcards are helpful is when there may or may not be a hyphen in a word or phrase, e.g., large scale structure vs. large-scale structure. Searching for large_scale structure returns both.

5. Search terms are applied against a combined string containing the speaker, talk title, series name, talk date (yyyy-mm-dd), and notes.

6. The Series page lists links to the Series web sites. In some case this may be a YouTube playlist or channel, but in most cases it's the site page for the conference, workshop, seminar series, etc.

7. Currently, a max of 100 talks are returned from a search. The suggestion is that if a search finds more than that, tighter search terms should be used. This is an arbitrary limit and can be adjusted if there is a good use case for it. The design of this site usually results in very good performance. If for some reason you want the entire .csv data file, it's available on the github repo.

8. Are you a researcher? Have you given cosmology-related research talks or academic lectures publicly-available online that aren't in this database? Or know of ones by others that should be included? (criteria: intended for an audience of other cosmology researchers or students.) If so, I'd like to know about them and would appreciate a message to either my twitter, or blueksy or mastodon account. My aim is to help fill a gap, since AFAIK there are no other sources that have attempted to collect this data as comprehensively and from as wide a range of sites as is included here.

9. For a link that directly provides the query results (e.g., if you want to bookmark a particular query), use querystring parameters.
