我在不返回任何结果的新表上有一个新索引。这很奇怪，我以前从未遇到过这个问题。其他索引（构建几乎相同）可以通过搜索 CLI 和我的 API 进行搜索。
这是我的conf文件
source topicalindex
{
type = pgsql
sql_host = localhost
sql_user = user
sql_pass = password
sql_db = db
sql_port = 5432 # optional, default is 3306
sql_query = SELECT id, topic, reference, start_ref, end_ref, see_also_html FROM my_topicalindex
sql_attr_uint = topic
sql_attr_uint = reference
}
index topicalindex_index
{
source = topicalindex
path = /path/to/data/topical_index
docinfo = extern
charset_type = utf-8
}
indexer
{
mem_limit = 32M
}
searchd
{
listen = 3312
log = /path/to/searchd.log
query_log = /path/to/query.log
read_timeout = 5
max_children = 30
pid_file = /usr/local/var/searchd.pid
max_matches = 30000
seamless_rotate = 1
preopen_indexes = 0
unlink_old = 1
}
这是证明数据库中有内容的摘录
[myself]:myapp(master)$ psql -d mydb -h localhost
psql (9.2.2)
Type "help" for help.
esv=# SELECT * FROM my_topicalindex LIMIT 1;
id | topic | reference | start_ref | end_ref | see_also_html
------+---------+--------------------+-----------+---------+---------------
2810 | Abraham | Genesis chs. 11–25 | 1011001 | 1025034 | blank
(1 row)
下面是索引过程：

然后——我的搜索结果为 0
[myself]:myapp(master)$ search -i topicalindex_index -a "Abraham"

index 'topicalindex_index': query 'Abraham ': returned 0 matches of 0 total in 0.000 sec

为什么我在搜索“Abraham”时得到 0 个结果。（奇怪的是，我在搜索“a”时确实得到了结果）
这是我的 conf 文件的问题吗？是别的吗？
编辑 我注意到，在搜索“a”时，它只搜索那些确实包含 see_also_html 字段内容的行。匹配数与每列具有数据的字段数相匹配。
