77 "*Non-nil means that Gnus will try to build threads by grabbing old headers.
78 If an unread article in the group refers to an older, already
79 read (or just marked as read) article, the old article will not
80 normally be displayed in the Summary buffer. If this variable is
81 t, Gnus will attempt to grab the headers to the old articles, and
82 thereby build complete threads. If it has the value `some', all
83 old headers will be fetched but only enough headers to connect
84 otherwise loose threads will be displayed. This variable can
85 also be a number. In that case, no more than that number of old
86 headers will be fetched. If it has the value `invisible', all
87 old headers will be fetched, but none will be displayed.
89 The server has to support NOV for any of this to work.
91 This feature can seriously impact performance it ignores all
92 locally cached header entries. Setting it to t for groups for a
93 server that doesn't expire articles (such as news.gmane.org),
94 leads to very slow summary generation."

111 "*nil means that Gnus won't gather loose threads.
112 If the root of a thread has expired or been read in a previous
113 session, the information necessary to build a complete thread has been
114 lost. Instead of having many small sub-threads from this original thread
115 scattered all over the summary buffer, Gnus can gather them.
117 If non-nil, Gnus will try to gather all loose sub-threads from an
118 original thread into one large thread.
120 If this variable is non-nil, it should be one of `none', `adopt',
121 `dummy' or `empty'.
123 If this variable is `none', Gnus will not make a false root, but just

149 common subjects, gathering might become saner."
154 "*Maximum length of subject comparisons when gathering loose threads.
155 Use nil to compare full subjects. Setting this variable to a low
156 number will help gather threads that have been corrupted by
157 newsreaders chopping off subject lines, but it might also mean that
158 unrelated articles that have subject that happen to begin with the
159 same few characters will be incorrectly gathered.

162 comparing subjects."
