MySQL街道地址模糊搜索

Question

有谁知道在 MySQL 数据库上进行模糊街道地址搜索的好脚本(或好策略)？关键问题是:

• 大写(简单——只需使用 LCASE)
• 标点符号(可以使用 REPLACE；不确定是否有更有效的选项)
• 缩写(这个很难——street = st，等等)

我希望能够匹配:123 Main st, unit B = 123 Main Street unit b

虽然它并不完美并且可能很慢，但您还是希望通过 REGEXP() 使用正则表达式。

这是匹配大多数情况(以及您的示例)的第一遍正则表达式:

(?isx)                  # search across multiple lines and ignore case
(                       # full match
  (                       # st number - what about number words like one or two?
    \d+
  )
  \s+                     # whitespace
  (                       # street name (one or more words)
    [a-z]+
    (?:
      \s+
      [a-z]+
    )*
  )
  \s+                     # whitespace
  (                       # street type
    al(?:y\.?|ley)          # aly, aly. or alley
  |
    ave(?:\.|nue)?          # ave, ave., or avenue
  |
    b(?lvd\.?|oulevard)     # blvd, blvd. or boulevard
  |
    c(?:t\.?|ourt)          # ct, ct. or court
  |
    cir(?:\c\.?|cle)?       # cir, circ, circ. or circle
  |
    cres(?:\.|cent)?        # cres, cres. or crescent
  |
    dr(?:\.|ive)?           # dr, dr. or drive
  |
    exp(?:y\.?|ressway)     # expy, expy. or expressway
  |
    f(?:wy\.?|reeway)       # fwy, fwy. or freeway
  |
    g(?:rdns\.?|ardens)     # grdns, grdns. or gardens
  |
    h(?:wy\.?|ighway)       # hwy, hwy. or highway
  |
    l(?n\.?|ane)            # ln, ln. or land
  |
    m(?:nr\.?|anor)         # mnr, mnr. or manor
  |
    m(?:trwy\.?|otorway)    # mtrwy, wtrwy. or motorway
  |
    pl(?:\.|ace)?           # pl, pl. or place
  |
    r(?:d\.?|oad)           # rd, rd. or road
  |
    st(?:\.|reet)?          # st, st. or street
  |
    t(?:pk\.?|urnpike)      # tpk, tpk. or turnpike
  |
    ter(?:\r?\.?|race)      # ter, ter., terr, terr. or terrace
  |
    tr(?:l.\?|ail)          # trl, trl. or trail
  |
    pike|park|walk|loop|bay|close|gate|highlands
  |
    row|way|oval|dell|rise|vale|byway|lawn
  )
  \,?                     # optional comma
  \s+                     # whitespace
  (                       # optional number, unit, apt or floor
    (
      \#                    # number
    |
      unit                  # unit
    |
      num(?:\.|ber)         # num, num. or number
    |
      ap(?:t\.?|artment)    # apt, apt. or apartment
    |
      fl(?:\.|oor)?         # fl, fl. or floor
    )
    \s+
    \d+
  )?
)

哪个会返回:

$1 - 完全匹配

$2 - 门牌号

$3 - 街道名称

$4 - 街道类型

$5 - 单位或 apt 号码(可选)

要在 mysql 中使用它，您需要删除所有注释(从“#”到 eol)，删除第一行(切换选项)，并将所有内容折叠到没有任何空格的单行。
