Rather than allow user-generated values to create crawlable URLs  -- which leads to infinite possibilities with very little value to searchers -- perhaps publish category pages for the most popular values, then include additional information so the page provides more value than an ordinary search results page. Alternatively, consider placing user-generated values in a separate directory and then robots.txt disallow crawling of that directory.

Si cet utilisateur arrive sur votre page pour lire ce contenu et qu'il ne le voit pas, il sera frustré et se dira que ce contenu ne correspond pas à son attente

si un tel contenu est caché, c'est peut-être qu'il n'est pas si important que cela pour l'utilisateur et donc que nous ne devrons pas non plus lui accorder autant d'importance. Alors, nous ne l'indexerons pas
