User not found by username

🤔 Problem

A user cannot be found by their username.

🌱 Solution

The first step should always be rebuilding the search index.

🧐 Other potential cause

If this is not leading to success, it might be that the user has a so-called stop word as a username. Confluence will ignore those common words (stop words), including 'and', 'the', 'or', and more, even if they are included within double quotes, in order to improve the quality of the search results.

Confluence uses the search engine Lucene. At the moment, the following words are defined as stop words:

... ,
"about", "after", "all", "also", "an", "and",
"another", "any", "are", "as", "at", "be",
"because", "been", "before", "being", "between",
"both", "but", "by", "came", "can", "come",
"could", "did", "do", "does", "each", "else",
"for", "from", "get", "got", "has", "had",
"he", "have", "her", "here", "him", "himself",
"his", "how","if", "in", "into", "is", "it",
"its", "just", "like", "make", "many", "me",
"might", "more", "most", "much", "must", "my",
"never", "now", "of", "on", "only", "or",
"other", "our", "out", "over", "re", "said",
"same", "see", "should", "since", "so", "some",
"still", "such", "take", "than", "that", "the",
"their", "them", "then", "there", "these",
"they", "this", "those", "through", "to", "too",
"under", "up", "use", "very", "want", "was",
"way", "we", "well", "were", "what", "when",
"where", "which", "while", "who", "will",
"with", "would", "you", "your",
...
